Abstract Selective CO 2 photoreduction to hydrocarbon fuels such as CH 4 is promising and sustainable for carbon‐neutral future. However, lack of proper binding strengths with reaction intermediates makes it still a challenge photocatalytic methanation both high activity selectivity.

The electrocatalytic oxidation of 5-hydroxymethylfurfural (HMF) is a promising method for the efficient production biomass-derived high-value-added chemicals. However, its practical application limited by: 1) low activity and selectivity caused by competitive adsorption HMF OH- 2) operational stability uncontrollable reconstruction catalyst.

Selective photocatalytic CO2 methanation provides an attractive avenue to address energy and environmental issues. However, impediments such as the sluggish adsorption activation of H2O molecules, along with unexpected intermediate desorption, greatly restrict activity selectivity methanation. To these issues, we devised a dual-active site catalyst comprising Cu single atoms (SAs) nanoclusters (NCs) supported on defective TiO2 (Cu1+NCs/BT). As result, remarkable CH4 98% yield 19.63 μmol...

The rate-determining step of the photoelectrochemical (PEC) water splitting is oxidation reaction at photoanode, which 4 orders magnitude slower than reduction photocathode. In a conventional process to accelerate oxidation, oxygen evolution cocatalysts (OECs) are usually used on surface photoanode. As an alternative strategy, we considered employing composite photoanode made up semiconductor and carbon spheres, for it expected that photogenerated electrons particles can be captured by...
