“…A significantly increased surface voltage was detected for the WCC/CdS catalyst, indicating enhanced high charge transfer efficiency (Figure c) . As shown in Figure d, the photocurrent density of WCC/CdS is much higher than that of pristine CdS, which is caused by the greatly promoted charge separation in WCC/CdS . As for the electrochemical impedance spectroscopy (EIS) curves, WCC/CdS has a smaller impedance semicircle than CdS, manifesting a lower charge transfer resistance that results in a more efficient transfer rate of charge carriers in the former (Figure e). , Moreover, the electrochemical hydrogen production activities of the CdS and WCC/CdS electrodes were further evaluated by using the linear sweep voltammetry (LSV) technique (Figure f).…”

It is highly desirable but challenging to optimize the electronic structure of an active site to realize moderate active site-H ads bond energies for boosting photocatalytic H 2 evolution. Herein, an interfacial engineering strategy is developed to simultaneously concentrate hydrogen species and accelerate the combination of an H ads intermediate to generate free H 2 by constructing W−WC− W 2 C (WCC) cocatalysts. Systematic investigations reveal that hybridizing with W 2 C creates electron-rich W active sites and effectively induces the downshift of the dband center of W in WC. Consequently, the strong W−H ads bonds on the surface of WC are weakened, thus promoting the desorption of H ads to rapidly produce free H 2 . The optimized 40-WCC/CdS photocatalyst exhibits a high hydrogen evolution rate of 63.6 mmol g −1 h −1 under visible light (≥420 nm) with an apparent quantum efficiency of 39.5% at 425 nm monochromatic light, which is about 40-fold of the pristine CdS. This work offers insights into the design of cocatalyst for highefficiency photocatalytic H 2 production.
