Solar-driven CO2 hydrogenation into multi-carbon products is a highly desirable, but challenging reaction. The bottleneck of this reaction lies in the C-C coupling C1 intermediates. Herein, we construct centre for intermediates via situ formation Co0 -Coδ+ interface double sites on MgAl2 O4 (Co-CoOx /MAO). Our experimental and theoretical prediction results confirmed effective adsorption activation by site to produce intermediates, while introduction electron-deficient state Coδ+ can effectively reduce energy barrier key CHCH* Consequently, Co-CoOx /MAO exhibited high C2-4 hydrocarbons production rate 1303 μmol g-1 h-1 ; total organic carbon selectivity 62.5 % under light irradiation with ratio (≈11) olefin paraffin. This study provides new approach toward design photocatalysts used conversion C2+ products.

Photocatalytic CO2 reduction holds great potential for alleviating global energy and environmental issues, where the electronic structure of catalytic center plays a crucial role. However, spin state, key descriptor properties, is largely overlooked. Herein, we present simple strategy to regulate states Co centers by changing their coordination environment exchanging species into stable Zn-based metal–organic framework (MOF) afford Co-OAc, Co-Br, Co-CN photoreduction. Experimental DFT calculation results suggest that distinct sites give rise different charge separation abilities barriers adsorption/activation in photocatalysis. Consequently, optimized Co-OAc with highest spin-state presents an excellent photocatalytic activity 2325.7 μmol·g–1·h–1 selectivity 99.1% CO, which are among best all reported MOF photocatalysts, absence noble metal additional photosensitizer.

Water electrolysis for H2 production is restricted by the sluggish oxygen evolution reaction (OER). Using thermodynamically more favorable hydrazine oxidation (HzOR) to replace OER has attracted ever-growing attention. Herein, we report a twisted NiCoP nanowire array immobilized with Ru single atoms (Ru1 -NiCoP) as superior bifunctional electrocatalyst toward both HzOR and hydrogen (HER), realizing an ultralow working potential of -60 mV overpotential 32 current density 10 mA cm-2 , respectively. Inspiringly, two-electrode electrolyzer based on overall splitting (OHzS) demonstrates outstanding activity record-high 522 at cell voltage 0.3 V. DFT calculations elucidate cooperative Ni(Co)-Ru-P sites in Ru1 -NiCoP optimize H* adsorption, enhance adsorption *N2 significantly lower energy barrier dehydrogenation. Moreover, self-powered system utilizing OHzS device driven direct fuel (DHzFC) achieve satisfactory rate 24.0 mol h-1 m-2 .
