摘要：

Sparked by the increasing energy crisis, much research has been focused on seeking board spectrum-driven photocatalysts for water splitting. Herein, the Ni₃(C₃N₃S₃)₂ coordination polymer was firstly synthesized by a simple wet-chemical method, as a novel board spectrum-driven photocatalyst for water splitting. The as-prepared Ni₃(C₃N₃S₃)₂ exhibited excellent photocatcalytic H₂-producing activity from the half-reaction of water splitting without the help of any sacrificial agents or cocatalysts, and the amounts of H2production are 65.3, 53.9 and 16.3 mmol corresponding to UV (l < 400 nm), visible(400 ≤ l ≤ 760 nm) and near-infrared (l > 760 nm) irradiation after 24 h, respectively. Another valuable finding is that after adding triethanolamine as a sacrificial donor, the average H₂ evolution efficiencies onNi₃(C₃N₃S₃)₂ were efficaciously increased by around 2-fold with the H₂ production value of 112.6, 93.3and 30.1 mmol for 24 h under the UV light, visible light and near-infrared light exposure, respectively. More importantly, the stability of Ni₃(C₃N₃S₃)₂ was effectively improved by means of triethanolamine. The results facilitate the increasing attention of narrow band gap non-noble metal coordination polymers treated as board spectrum-driven photocatalysts for expanding the utilization of solar light.
