超广谱吸收和高效产生可用的电荷载流子是有前途的半导体基光催化剂的两个基本要求，以实现太阳能到燃料转换的最终目标。在这里，报道了一种具有W18 O 49/g-C3 N4异质结构的迷人的非金属等离子体Z-方案光催化剂，它可以有效地收集从UV到近红外区域的光子能量，同时具有改进的电荷载流子动力学，以促进长寿命活性电子的产生，用于光催化还原质子为H2。通过结合理论模拟，在这种二元异质结构中，证明了在Z-Z-方案电荷载流子分离和金属类局域表面等离子体激元共振诱导的“热电子”注入过程之间的独特协同效应。
Ultrabroad‐spectrum absorption and highly efficient generation of available charge carriers are two essential requirements for promising semiconductor‐based photocatalysts, towards achieving the ultimate goal of solar‐to‐fuel conversion. Here, a fascinating nonmetal plasmonic Z‐scheme photocatalyst with the W18O49/g‐C3N4heterostructure is reported, which can effectively harvest photon energies spanning from the UV to the nearinfrared region and simultaneously possesses improved charge‐carrier dynamics to boost the generation of long‐lived active electrons for the photocatalytic reduction of protons into H2. By combining with theoretical simulations, a unique synergistic photocatalysis effect between the semiconductive Z‐scheme charge‐carrier separation and metal‐like localized‐surface‐plasmon‐resonance‐induced “hot electrons” injection process is demonstrated within this binary heterostructure.
