Advances and Outlook of Metal–Organic Frameworks as High-Performance Electrocatalysts for Hydrogen Evolution Reaction: A Minireview

“…The addition of AB was found to be beneficial, leading to improved performance of the resulting mixtures under acidic conditions for the HER. Within the range of various composite compositions investigated, the AB&Co-Cl 4 -MOF (3:4) composite was identified as the most effective in terms of HER performance, exhibiting a smaller overpotential of 283 mV, a lower Tafel slope of 86 mV·dec –1 , and exceptionally long-lasting performance over 24 h. In previous years, bimetallic conductive MOFs came to the fore as an auspicious group of electrocatalysts . This approach involves incorporating two different metals in the MOF which can provide synergistic effects that enhance the material’s capacity to catalyze electrochemical processes .…”

Historical and contemporary perspectives on metal–organic frameworks for gas sensing applications: a review

“…Hydrogen gas (H 2 ) plays an integral role in energy production. 130,131 The signicant uses for H 2 include NH 3 synthesis [132][133][134] and the production of methanol from carbon monoxide. 135 H 2 gas is also a sustainable fuel source that drives intense research for the transition from fossil fuels to renewable energy sources.…”

Fluorination of Covalent Organic Framework Reinforcing the Confinement of Pd Nanoclusters Enhances Hydrogen Peroxide Photosynthesis

“…A key strategy for stabilizing the metal-isolated clusters is to physically confine them into porous supports, such as zeolites, , mesoporous silica, , hollow mesoporous carbon, , metal–organic frameworks (MOFs), , and covalent organic framework (COFs). − However, the simple physical confinements suffer from the stability decay of the catalyst during the catalytic process. Strong metal–support interaction (MSI) has been proved to stabilize metal-isolated clusters and promote electron transport simultaneously, which affects the catalytic durability and activity. , Rational design of support at the molecular level to increase the MSI is quite interesting in stabilizing metal-isolated clusters and tailoring its catalytic activity.…”
