The rapid depletion of fossil fuels and environmental pollution has motivated scientists to cultivate renewable and green energy sources. The hydrogen economy is an emerging replacement for fossil fuels, and photocatalytic water splitting is a suitable strategy to produce clean hydrogen fuel. Herein, the photocatalyst (PdO.TiO) is introduced as an accelerated photoelectrochemical oxygen evolution reaction (OER). The catalyst showed significant improvement in the current density magnitude from 0.89 (dark) to 4.27 mA/cm (light) during OER at 0.5 V applied potential. The as-synthesized material exhibits a Tafel slope of 170 mVdec and efficiency of 0.25% at 0.93 V. The overall outcomes associated with the photocatalytic activity of PdO.TiO demonstrated that the catalyst is highly efficient, thereby encouraging researchers to explore more related catalysts for promoting facile OER.
化石燃料的迅速枯竭和环境污染促使科学家们培养可再生和绿色能源。氢能经济是一种新兴的化石燃料替代品，光催化水分解是生产清洁氢气燃料的一种合适策略。在此，引入光催化剂（PdO.TiO）作为加速光电化学氧气析出反应（OER）的方法。在施加 0.5 V 应用电位的 OER 过程中，催化剂的电流密度从 0.89（暗）显著提高到 4.27 mA/cm（光）。所合成的材料表现出 170 mVdec 的塔菲尔斜率和在 0.93 V 时 0.25%的效率。与 PdO.TiO 的光催化活性相关的整体结果表明，该催化剂具有高效性，从而鼓励研究人员探索更多相关的催化剂来促进简便的 OER。
