A non-classical Ru-based polyoxometalate, NaH[{Ru(bpy)Cl}O(PWO)]·10HO (1), was successfully constructed from mono-vacant heteropolytungstates [PWO] and [Ru(bpy)Cl]. Compound 1 has strong light trapping ability, and the yield of aniline reduced from nitrobenzene under visible light ( > 400 nm) can reach 99.8%. In addition, a range of extended experiments have demonstrated that compound 1 is an effective and stable heterogeneous catalyst in the reaction of nitrobenzene reduction.

The bottom-up construction of leaf-like materials capable of using visible light and water to produce oxygen and chemical energy is a major goal of artificial photosynthesis. In this work, we show that robust artificial cells (protocells) prepared by the membranization of polymer/nucleotide coacervate droplets with a bio-inspired Ru-based polyoxometalate (POM) catalytic oxygen-evolving center are capable of continuous light-assisted water oxidation at room temperature. We present a method to electrostatically assemble millions of the photocatalytic protocells into tissue-like protocellular sheets and spheroids and demonstrate that the protocellular assemblies exhibit enhanced rates of photocatalytic water oxidation compared with individual protocells.

Despite intensive studies over decades, the development of electrocatalysts for acidic water splitting still relies on platinum group metals, especially Pt and Ir, which are scarce, expensive, and poorly sustainable. Because such problems can be alleviated, Ru-based bifunctional catalysts such as rutile RuO have recently emerged. However, RuO has a relatively low activity for hydrogen evolution reactions (HER) and low stability for oxygen evolution reactions (OER) under acidic conditions.

The potential of converting traditional biomass into low-cost HER catalysts has broad application prospects. In this paper, fungus is used as a carbon-based carrier. The bimetallic catalyst RuM-C (M = V, Mo, W, Zn, Cu) was synthesized under inert gas protection at high temperature.

Irradiation of the Keggin-type [PWO{Ru(NO)}] () polyoxometalate in CHCN results in rapid NO ligand elimination with the formation of [PWO{Ru(CHCN)}] (). This complex offers an easy entry into the Ru-based chemistry of the {PWRu} complex. Attempts to substitute N for CHCN in the presence of an NaN excess lead a variety of products: (i) [PWO{Ru(N)}] (); (ii) [PWO{Ru(NHC-CH)}] () as a click-reaction product; and (iii) [PWO{Ru(N)}] ().
