A novel two-step electrodeposition method is presented to fabricate a high-performance CoS/graphene hybrid network with nanosheet structure on Ni foam.
Earth-abundant electrocatalysts are desirable for the efficient and selective reduction of CO2 to value-added chemicals. Here, a low-cost porous Zn electrocatalyst is synthesized using facile electrodeposition method boost performance electrocatalytic reaction (CO2RR). In an H-cell reactor, catalyst can convert CO at remarkably high faradaic efficiency (FE, ∼95%) current density (27 mA cm–2) −0.95 V versus reversible hydrogen electrode. Detailed electrokinetic studies demonstrate that...

Herein, it is revealed that polymers used as binders can effectively modulate accessibility relative H O at vicinity thus performance RR.

Metal complexes have shown impressive selectivity and activity as catalysts for electrochemical CO2 reduction (CO2RR), yet the nature of their active sites under operating conditions remains elusive. Herein, by using in situ Raman, X-ray photoelectron spectroscopy, advanced electron microscopy combination with density functional theory calculations, we reveal that copper phthalocyanine (CuPc) reconstructs during CO2RR, which proceeds through demetalation CuPc to Cu atoms followed...
China has also experienced a phenomenon of counter-urbanisation. Many urban residents have moved to suburban and even remote rural areas for living, establishing operating businesses over the past decade. However, research is scarce on counter-urbanisation trend in China. This paper investigates driving forces behind migration China's high-and-middle-income groups Yangtze River Delta region their impacts villagers development. The contends that serves as an important pathway revitalisation....

CO-selective metals (e.g., Ag) on Cu catalysts improve the selectivity of multi-carbon (C2+) products in electrochemical CO2 reduction. However, origin improvement remains unclear due to convolution tandem and interface effects. Here, Ag@C@Cu core-shell were synthesized, which thin carbon interlayer inhibited direct interaction between Ag while still allowing reduction Ag, thus isolating effect from other This catalyst produced higher ratios ethanol ethylene relative monometallic catalyst,...
Cu-based bimetallic catalysts have attracted great attention for the reverse water gas shift (RWGS) reaction due to their high activity and selectivity. This work reports application of Cu–In RWGS demonstrates that promotion effect In on Cu is support sensitive. The Cu–In/ZrO2 catalyst exhibited significantly higher CO2 conversion than Cu/ZrO2 catalyst, whereas over Cu–In/CeO2 was much lower Cu/CeO2. reasons support-dependent revealed by systematic characterizations. On ZrO2 support, formed...
