Abstract:
Overall water splitting is an effective strategy for converting solar or electrical energy into clean hydrogen energy. However, the sluggish kinetics of the oxygen evolution reaction (OER) within the water-splitting process acts as a constraint on the overall efficiency of energy transformation. In this study, single-metal atom (Fe, Co, and Ni) and the corresponding bimetallic atoms were loaded onto the (100) planes of poly(triazine imide) intercalated with lithium chloride through metal-support interactions (MSI) and constructed hydroxyl-modified catalysts. We examined the OER process on both pristine and hydroxyl-modified catalyst surfaces, and the results demonstrated that the hydroxyl-modified catalysts had significantly greater catalytic activity for OER compared to the pristine surfaces. The conclusion drawn is that hydroxylation alters the electronic structure of the catalysts, thereby enhancing their OER activity. This study has deepened our understanding of the role of hydroxyl groups in the catalytic process and has provided a viable approach for developing efficient OER catalysts for effective water splitting.

Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.

Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.
