摘要：The successful design of photocatalytic hydrogen generation from water relies on a thorough understanding of the role of cocatalyst. The photoreactivity was studied as a function of the cluster size of the oxidized platinum cocatalyst. The maximum turnover frequency is found on the smallest-sized cocatalyst. This effect can be attributed to the size-dependent proton adsorption.
