Consumption of contaminated water can have detrimental effects on the health every living organism earth. There is, thus, a need to develop novel materials and technologies purify water. Water is also source hydrogen, clean renewable fuel that be generated through action photoactive catalyst earth's abundant solar energy. Using photocatalysis, we by removing organic pollutants photodegradation reaction (oxidation) produce hydrogen (H2) evolution (reduction). However, combine these two...
Abstract Here, four MOFs, namely Sc-TBAPy, Al-TBAPy, Y-TBAPy, and Fe-TBAPy (TBAPy: 1,3,6,8-tetrakis( p -benzoic acid)pyrene), were characterized evaluated for their ability to remediate glyphosate (GP) from water. Among these materials, Sc-TBAPy demonstrates superior performance in both the adsorption degradation of GP. Upon light irradiation 5 min, completely degrades 100% GP a 1.5 mM aqueous solution. Femtosecond transient absorption spectroscopy reveals that exhibits enhanced charge...
Abstract Photocatalytic hydrogen production offers an alternative pathway to establish a sustainable energy economy, utilizing the Earth's natural sunlight and water resources address environmental concerns associated with fossil fuel combustion. While numerous photoactive materials exhibit high potential for generating from water, synergy achieved by combining two different complementary properties in form of heterojunctions can significantly enhance rate quantum efficiency. Our study...
Abstract Iron is a promising candidate for cost‐effective anode large‐scale energy storage systems due to its natural abundance and well‐established mass production. Recently, Fe‐ion batteries (FeIBs) that use ferrous ions as the charge carrier have emerged potential solution. The electrolytes in FeIBs are necessarily acidic render more anodically stable, allowing wide operation voltage window. However, iron suffers severe hydrogen evolution reaction with low Coulombic efficiency (CE) an...

Metal–organic framework-based semiconductors have shown great promise for the production of a green fuel, hydrogen, using two abundant resources: sun and water.
Herein, we report the synthesis of photoactive polymeric organo-sulfur (POS) materials. These polymers absorb light in ultraviolet/visible and near-infrared region solar spectrum, upon irradiation, they reduce water to hydrogen (H2 ). The decoration POS materials with nitrile (-CN) groups is found be critical factor for enhanced interactions co-catalyst, Ni2 P, leading greater H2 evolution rates compared nitrile-free material.
Metal–organic frameworks (MOFs) are regarded as promising materials for energy applications, particularly in photocatalytic hydrogen (H2) production. This is due to their structural architectures that facilitate charge transfer, and tunable porous light absorption properties. However, the many characteristics of MOFs including crystal morphology sizes, surface facets, porosity, properties, optical band gaps, can significantly influence activity, presenting challenges achieving...
Metal–organic frameworks (MOFs) have emerged as a highly tunable class of porous materials with wide-ranging applications from gas capture to photocatalysis. Developing these exciting properties their fullest extent requires thorough mechanistic understanding the structure–function relationships. We implement an ultrafast spectroscopic toolset, femtosecond transient absorption and stimulated Raman spectroscopy (FSRS), elucidate correlated electronic vibrational dynamics two isostructural...
The impact of metals within a family isostructural metal-organic frameworks (MOFs) on the adsorption and photodegradation herbicide glyphosate (GP) is presented in this study. Four MOFs, namely Sc-TBAPy, Al-TBAPy, Y-TBAPy, Fe-TBAPy (TBAPy: 1,3,6,8-tetrakis(p-benzoic acid)pyrene), were characterized evaluated for their ability to remediate GP from water.
