Summary: The properties and reactivity of metal complex photocatalysts for solar-to-fuel conversion can be controlled by the molecular design of their ligands. In this study, rhenium(I) tricarbonyl polypyridyl compounds with different N-heterocyclic ligands were investigated as photocatalysts for reducing CO2 to CO. These complexes showed exceptional photocatalytic performance, with significantly increased TONCO values compared to the unsubstituted parental complex. The presence of N-heterocyclic substituents enhanced the visible-light absorption properties, favored the kinetics and thermodynamics of the photocatalysis, inhibited deactivation of the photocatalysts, and unlocked an alternative CO2 photoreduction pathway.

Summary: In this study, Ag2S/PCNNVs nanoreactors were developed by coating silver sulfide quantum dots (Ag2S QDs) onto the surface of porous graphitic carbon nitride nano vesicles (PCNNVs) through a simple calcination method. These nanoreactors showed efficient photothermal-assisted photocatalytic hydrogen (H2) evolution under simulated/real sunlight irradiation. The optimized 3% Ag2S/PCNNVs sample exhibited a hydrogen production rate of 34.8 mmol h-1 g-1, which was 3.5 times higher than that of bare PCNNVs. The enhanced activity of the Ag2S/PCNNVs composite system is attributed to the coupling of the photothermal conversion performance of Ag2S QDs and the thermal insulation performance of PCNNVs based on the plasmonic coupling-boosted photothermal nanoreactor. This study presents a promising strategy for the development of high-efficient photothermal-assisted photocatalysts.

Summary: CO2 reforming of methanol for producing hydrogen was experimentally studied using a fixed-bed reactor with 10%Ni/SiO2 catalyst. The catalyst was fully reduced and had a surface area of 240.5 m(2)/g during H-2 activation. The methanol conversion significantly improved from 52% to 99% with increasing temperature from 450 to 550 degrees C due to the endothermic nature of CO2 reforming. The H-2/CO ratios ranged from 1.65 to 1.76 at different reaction temperatures, which are preferred for long-chain hydrocarbons generation in Fischer-Tropsch production. The catalytic activity remained stable within 8 hours on-stream due to the maintenance of Ni-0 metallic phase during CO2 reforming of methanol. The catalytic deterioration was not observed because of the concomitant CO2 gasification of surface carbonaceous species during reaction.
