Hydrogen Production via Electrolysis of Wastewater.

The high energy consumption of traditional water splitting to produce hydrogen is mainly due to complex oxygen evolution reaction (OER), where low-economic-value O gas is generated. Meanwhile, cogeneration of H and O may result in the formation of an explosive H/O gas mixture due to gas crossover. Considering these factors, a favorable anodic oxidation reaction is employed to replace OER, which not only reduces the voltage for H production at the cathode and avoids H/O gas mixture but also generates value-added products at the anode.

Enhanced carbon dioxide adsorption and carrier separation over amine functionalized zirconium metal organic framework/gold/indium oxide for boosting photocatalytic carbon dioxide reduction.

Photocatalytic CO conversion is a prospective way to mitigate greenhouse effect. InO is widely used in the resource conversion of CO, but still exists a few drawbacks containing limited CO capture and activation, narrow light absorption range, low charge separation and utilization. To overcome these disadvantages, an NH-UiO-66/Au/InO composite photocatalyst is built, with Au nanoparticles and NH-UiO-66 decorated on the surface of InO nanorods.

Pulsed-Laser-Triggered Piezoelectric Photocatalytic CO Reduction over Tetragonal BaTiO Nanocubes.

The recombination of photoinduced carriers in photocatalysts is considered one of the biggest barriers to the increase of photocatalytic efficiency. Piezoelectric photocatalysts open a new route to realize rapid carrier separation by mechanically distorting the lattice of piezoelectric nanocrystals to form a piezoelectric potential within the nanocrystals, generally requiring external force (e.g.
