Semiconductor‐based step‐scheme (S‐scheme) heterojunctions possess many merits toward mimicking natural photosynthesis. However, their applications for solar‐to‐chemical energy conversion are hindered by inefficient charge utilization and unsatisfactory surface reactivity. Herein, two synergistic protocols are demonstrated to overcome these limitations based on the construction of a hollow plasmonic...
Embedding Nano‐Piezoelectrics
In article number 2302717, Song Bai and co‐workers propose an innovative strategy for better coupling of piezocatalysis and photocatalysis by embedding nano‐piezoelectrics into the heterointerfaces of S‐scheme heterojunction photocatalysts. The embedded piezoelectrics intensify the S‐scheme recombination of weak carriers and accelerate the separation of powerful ones,...
Step‐scheme (S‐scheme) heterojunctions have exhibited great potential in photocatalysis due to their extraordinary light harvesting and high redox capacities. However, inadequate S‐scheme recombination of useless carriers in weak redox abilities increases the probability of their recombination with useful ones in strong redox capabilities. Herein, a versatile protocol is demonstrated to overcome this...
Construction of core–shell semiconductor heterojunctions and plasmonic metal/semiconductor heterostructures represents two promising routes to improved light harvesting and promoted charge separation, but their photocatalytic activities are respectively limited by sluggish consumption of charge carriers confined in the cores, and contradictory migration directions of plasmon‐induced hot electrons...
Earth‐abundant layered tungsten disulfide (WS2) is a well‐known electrocatalyst for acidic hydrogen evolution, but it becomes rather sluggish for alkaline hydrogen or oxygen evolution due to the low‐density edge sites, poor conductivity, and unfavorable water dissociation behavior. Here, an interfacial engineering strategy to construct an efficient bifunctional electrocatalyst by in situ growing N‐doped...
