Solar-powered seawater production of clean hydrogen fuel is highly prospective. In this work, NiC/MnCdS (NCMCS) Schottky junctions with excellent visible-light correspondence and photogenerated carrier separation properties are constructed using electrostatic attraction. The material achieves a hydrogen evolution rate of 6472.9 μmol h g in simulated seawater, which is 11 times higher than that of a single MnCdS (MCS). More attractively, the composite exhibits excellent hydrogen evolution rates in natural river water, groundwater and tap water, with significantly enhanced practical applicability. The underlying hydrogen evolution mechanism was extrapolated from a combination of experimental and theoretical calculations. The present work provides a low-cost and efficient hydrogen evolution photocatalyst for practical application, which can help promote the efficient conversion of solar-hydrogen energy.
太阳能驱动海水制清洁氢燃料极具前景。在这项工作中，利用静电吸引构建了具有优异可见光响应和光生载流子分离性能的NiC/MnCdS（NCMCS）肖特基结。该材料在模拟海水中的析氢速率达到6472.9 μmol h g，比单一的MnCdS（MCS）高11倍。更具吸引力的是，该复合材料在天然河水、地下水和自来水中均表现出优异的析氢速率，实际适用性显著增强。通过实验和理论计算相结合推断出潜在的析氢机制。本工作为实际应用提供了一种低成本、高效的析氢光催化剂，有助于推动太阳能-氢能的高效转化。
