Nanostructured H2 evolution cocatalysts are able to promote charge separation and thus enhance the efficiency of the photocatalytic H2 evolution reaction (HER). However, the nanosized cocatalyst particles are easily detached from the surfaces of semiconductors or severely aggregated in reaction systems, which not only greatly reduces the photocatalytic HER efficiency during long-term use but also greatly
