“…Seyler et al have recently published an impressive series of solid-state photocatalyst libraries synthesized and screened for hydrogen production with the greatest diversity of combinations presented to date for photocatalysts [30]. Using a liquid-phase dispensing robot, mixtures of sol-gel precursors were used to create binary and ternary oxides containing an enormous variety of metals, including Li, Na, K, Ba, Bi, Co, Mg, Mn, Nd, Ni, Sb, Sr, Y, Yb, Zn, Al, Fe, La, Zr, V, Ta and Ti.…”
