Climate change and rising global energy demands have prompted an urgent search for new renewable energy solutions. Molecular fuels offer an attractive option for resolving this issue owing to the high energy density that can be concentrated within chemical bonds. In order to expand the nature of metal in complexes modelling the active centres of Hydrogenase, a Pd(II) complex with ligand containing nitrogen and sulphur donor atoms was synthesized (Fig.1). The compound shows electrocatalytic proton reduction in the cyclic voltammetry experiment (Fig.2). The analogical investigation was realised in the presence of trifluoroacetic acid (TFA) (Fig.3). Linear dependence of ic/ip – f([TFA)] permits to determine the value of turnover frequency (TOF ≥ 1800 s-1).figureFigure 1. View of the molecule of PdL.Figure 2.
