Electrochemical CO2 reduction (ECR) to valuable chemicals and fuels using renewable energy is a promising way to reduce carbon emission. Herein, Sn-based films were electrodeposited on Ag foil surfaces (Sn/Ag-y)...
Transforming carbon dioxide (CO2) into valuable chemical products or carbonaceous fuels is a crucial strategy for addressing the impact of global climate change and energy challenges. Electrochemical CO2 reduction reaction (eCO2RR) shows promise in this regard, but challenges remain in the eCO2RR, such as poor electrocatalytic activity and low sele...
Electrochemical CO2 reduction is a promising method for converting atmospheric CO2 into valuable low‐carbon chemicals. In this study, a crystalline cadmium sulfide/amorphous cadmium hydroxide composite was successfully deposited on the carbon paper substrate surface by in‐situ chemical bath deposition (named as c‐CdS/a‐Cd(OH)2/CP electrodes) for th...
The electrocatalytic CO2 reduction (ECR) to produce valuable fuel is a promising process for addressing atmospheric CO2 emissions and energy shortages. In this study, Cl‐anion doped cadmium sulfide structures were directly fabricated on a nickel foam surface (Cl/CdS‐NF) using an in situ hydrothermal method. The Cl‐anion doping could significantly i...
Electric‐driven conversion of carbon dioxide (CO2) to carbon monoxide (CO) under mild reaction conditions offers a promising approach to mitigate the greenhouse effect and the energy crisis. Surface engineering is believed to be one of the prospective methods for enhancing the electrocatalytic activity of CO2 reduction. Herein, hydroxyl (OH) groups...
Metal‐organic frameworks (MOFs) as a promising platform for electrocatalytic CO2 conversion are still restricted by the low efficiency or unsatisfied selectivity for desired products. Herein, zirconium‐based porphyrinic MOF hollow nanotubes with Cd sites (Cd‐PCN‐222HTs) are reported for electrocatalytic CO2‐to‐CO conversion. The dispersed Cd specie...
The electroreduction of carbon dioxide (CO2) is a sustainable method for generating valuable chemicals; however, avoiding unwanted hydrogen (H2) production during the electrolysis is a major challenge. Coproduction of carbon monoxide (CO) and H2 to produce syngas is an effective strategy for solving this problem, and syngas with a desired CO/H2 rat...
Electroreduction of CO2 is a sustainable approach to produce syngas with tunable CO/H2 ratios, which are required as specific reactants for the optimization of desired products. Herein, ZnO-d and ZnO-n...
Electrocatalytic reduction of CO2 over zeolitic imidazolate frameworks (ZIFs) generally has poor activity and low CO Faradaic efficiency due to the poor contact between conductive substrate and ZIFs synthesized by ex‐situ method. Here, ZIF‐8 films on Zn foils (ZIF‐8/Zn) fabricated by in‐situ electrochemical deposition were used for CO2 electroreduc...
The design of robust electrocatalysts for CO2 electroreduction with large current density and high selectivity for desired production is a crucial step in realizing carbon-neutral energy cycle and producing more...

Electrochemical reduction of CO2 is a very promising route to realize carbon cycle and alleviate energy shortage. Herein, the porous zinc oxide nanosheets with hydroxyl groups on carbon paper substrates (ZnO(OH)/CP‐x,×represents the deposition time) were proved to be excellent catalysts for CO2 electroreduction to CO. As far as we know, the hydroxy...
Background:
Two studies have suggested that severe prolonged nausea and vomiting during pregnancy is associated with emotional and behavioral problems in offspring, with smaller sample size and short-term follow-up. Moreover, little information is available on the role of the brain structure in the associations.
Methods:
In a US-based cohort, th...

... The preparation of different electrodes: The Cd/CP, Cd/Cd(OH) 2 / CP, Cd/CdO/CP, and Cd(OH) 2 /CP electrodes were prepared as following. [21,36] Briefly, 5 mg of above obtained Cd, Cd/Cd(OH) 2 , Cd/ CdO, or Cd(OH) 2 nanomaterials and 0.5 mg of carbon black (Vulcan XC72) were added into 1.5 mL of acetone to prepare homogeneous ink with a ultrasonic processing. The as-prepared homogeneous ink (300 μL) was dispersed onto the CP substrate (1×1 cm 2 ), and then the CP substrate was dried under room temperature. ...
... In particular, the 10 nm n + p Si/GaN/Au photoelectrode can generate a desirable CO/H 2 ratio of approximately 1:2 [146], which is suitable for the industrial production of methanol and long-chain hydrocarbons via F-T process. CO is also the main product of molecular catalysts and metal-organic frameworks (MOF) [156,157]. For example, Wen et al. [147] presented a novel strategy for preparing hybrid photoelectrodes by immobilizing a molecular cobalt catalyst onto n + p Si electrodes protected by multi-walled carbon nanotubes (CNTs) wrapped around TiO 2 , utilizing π-π stacking interactions (Figure 8e). ...
... [8,[15][16][17][18] The most common products of eCO 2 R are formate and CO, which both are economically competitive to current fossil-based production routes. [5,[19][20][21][22][23][24] In addition, a C 2 + product, such as acetate, is high added-value, thus an alternative, green, electrochemical synthesis route for this chemical is of industrial interest. [25] The electrochemical production of acetate from waste CO 2 is still challenging, considering the complexity of the reduction reaction À 8 electron equivalents involved, while CO and formate require only 2 electron equivalents. ...
... Most of what is known relates to neurodevelopmental disorders [7][8][9]. A study of nearly 470,000 children from California found that maternal hyperemesis gravidarum was associated with 1.53 times the risk of autism spectrum disorder compared with no maternal hyperemesis [7]. ...
