The presence of antibiotic contaminants in water reservoirs and aquatic environments poses considerable risks to public and ecosystem health. Despite its high mineralization efficiency and environmental friendliness, photocatalytic technology has limited practical applications due to low energy efficiency, intermittent operation, and inconvenient c...

The cycloaddition reaction of carbon dioxide with propylene oxide captures considerable attention owing to its environmental friendliness, economy and 100% atomic utilization. Homogeneous metal catalysts exhibit excellent performance in cycloaddition reactions, but their widespread applications are limited by complicated preparation and recovery pr...

Developing a promising strategy to improve the limited selectivity and activity of traditional Pd-Cu bimetallic catalysts for CO2 hydrogenation to methanol (CH3OH) remains a grand challenge. By using density functional theory calculations, we discovered that introducing imine groups on the Cu1/Pd(111) surface through a condensation reaction of alde...

Full-spectrum photofixation of N2 with remarkable NH3 production rate of 228 μmol/(g·h) was achieved by W atoms doped Ti3C2TxMXene (W/Ti3C2Tx-U) catalyst without sacrificial agents at room temperature. The effects of W doping and ultrasonic intercalation of Ti3C2TxMXene were studied. Scanning transmission electron microscope, electron spin resonanc...

Photocatalytic aerobic oxidation by using oxygen molecules (O2) as green and low-cost oxidants is of great attraction, where the introduction of irradiation has been proved as an efficient strategy to lower reaction temperature as well as promote catalytic performance. Moreover, the oxygen vacancies (OVs) of catalyst are highly active sites to adso...

Abundant and affordable methane is not only a high‐quality fossil fuel, it is also a raw material for the synthesis of value‐added chemicals. Solar‐energy‐driven conversion of methane offers a promising approach to directly transform methane to valuable energy sources under mild conditions, but remains a great challenge at present. In this Review,...

As a promising hydrogen carrier, formic acid (HCOOH) is renewable, safe and nontoxic. Although noble-metal-based catalysts have exhibited excellent activity in HCOOH dehydrogenation, developing non-noble-metal heterogeneous catalysts with high efficiency remains a great challenge. Here, we modulate oxygen coverage on the surface of Ti3C2Tx MXenes t...

Utilization of infrared (IR)/near-infrared (NIR) light paves an opportunity to improve the efficiency of N2 photofixation under full-spectrum irradiation, but remains as a grand challenge. Herein, a highly active photocatalyst towards NIR light-driven N2 photofixation was successfully developed by construction of plasmonic Ti3C2Tx MXene and TiO2 hy...
