Abstract |
Photocatalytic water splitting by semiconductor nanostructures is a challenging chemical process to harnessing abundant solar energy and to get clean hydrogen fuel. To that end, the photocatalyst consist of efficient light harvesting semiconductor nanostructures as photo absorbers and noble metal free robust co-catalysts have gained much attention. Here, we designed a noble metal free nanohybrid consist of CdS nanorods as a photo absorbers and CoSe2 derived from nanocages as a co-catalyst. Benefiting from the abundant catalytically active sites the designed nanohybrid exhibit remarkable photocatalytic hydrogen evolution performance (82.97 mmol∙h–1∙g–1) and prominent recycling stability under solar light irradiation. The key role of co-catalyst, catalyst dosage, scavenger concentration and origin of photocatalytic hydrogen evolution rate is thoroughly explored. Finally, we expect that the demonstrated new noble metal free nanohybrid design strategy may bring novel insights to develop low-price noble metal free photocatalysts for H2 production. |
