The loss of catalytic activity or selectivity over time of production affects the cost of catalyst replacement, process shutdown, and product quality and quantity. Numerous researchers have reported that noble metal-based catalysts, such as Pt, Rh, Pd, Ru

• cocatalysts, such as Pt, Rh, NiO, and RuO2. These cocatalysts are mainly helpful to introduce the active sites on the photocatalyst surface, to facilitate the electron transfer from the CB of excited semiconductor, and hence, to enhance the process of H2 generation [11]. However, the sacrificial agents

In water splitting reactions, generally noble metals (e.g., Pt, Rh) and some metal oxides (e.g., NiO) act as the cocatalyst and these are loaded on the surface of

In the past it was assumed that Pt–Rh is immiscible at low temperatures [1][2], but theoretical studies revealed that Pt–Rh
