Delicate electrochemical active surface area (ECSA) engineering over the exposed catalytic interface and surface topology of platinum‐based nanomaterial represents an effective pathway to boost its catalytic properties toward the clean energy conversion system. Here, for the first time, the facial and universal production of dendritic Pt‐based nanoalloys (Pt‐Ni, Co, Fe) with highly porous feature...
Single atomic Pt catalysts exhibit particularly high hydrogen evolution reaction (HER) activity compared to conventional nanomaterial‐based catalysts. However, the enhanced mechanisms between Pt and their coordination environment are not understood in detail. Hence, a systematic study examining the different types of N in the support is essential to clearly demonstrate the relationship between Pt...
Single‐atom catalysts (SACs) have attracted significant attention due to their superior catalytic activity and selectivity. However, the nature of active sites of SACs under realistic reaction conditions is ambiguous. In this work, high loading Pt single atoms on graphitic carbon nitride (g‐C3N4)‐derived N‐doped carbon nanosheets (Pt1/NCNS) is achieved through atomic layer deposition. Operando X‐ray...
In article number 1705538, Jinlong Gong and co‐workers from Tianjin University describe the construction of ultrathin defect‐enriched three‐dimensional Se‐(NiCo)Sx/(OH)x nanosheets for overall water splitting through a facile Se‐induced hydrothermal treatment. Through morphological optimization, defect engineering, and tailoring of the electronic structure, the nanosheets deliver a current density...
The exploration of highly efficient electrocatalysts for both oxygen and hydrogen generation via water splitting is receiving considerable attention in recent decades. Up till now, Pt‐based catalysts still exhibit the best hydrogen evolution reaction (HER) performance and Ir/Ru‐based oxides are identified as the benchmark for oxygen evolution reaction (OER). However, the high cost and rarity of these...
