“…For N 1s spectra, the binding energy of Fe@Co-CP-2 shifted, attributed to the change in chemical environment after introduction of Fe (Figure d). In the O 1s spectra, the Co-CP revealed the three peaks to be CO (532.95 eV), C–O (531.79 eV), and Co–O (531.06 eV), respectively . Fe@Co-CP-2 revealed the three peaks to be CO (532.88 eV), C–O (531.73 eV), and Co–O (531.01 eV) (Figure e).…”

The solar light-responsive Fe-doped Co-based coordination polymer (Fe@Co-CP) photocatalyst was synthesized under mild conditions.[Co(4-padpe)(1,3-BDC)] n (Co-CP) was first constructed using mixed ligands through the hydrothermal method. Then, Fe was introduced into the Co-CP framework to achieve the enhanced photocatalytic activity. The optimal Fe@Co-CP-2 exhibited excellent catalytic degradation performance for norfloxacin and ciprofloxacin under sunlight irradiation without auxiliary oxidants, and the degradation rates were 91.25 and 92.66% in 120 min. These excellent photocatalytic properties were ascribed to the generation of the Fe−O bond, which not only enhanced the light absorption intensity but also accelerated the separation efficiency of electrons and holes, and hence significantly improved the photocatalytic property of the composites. Meanwhile, Fe@Co-CP-2 displayed excellent stability and reusability. In addition, the degradation pathways and intermediates of antibiotic molecules were effectively analyzed. The free radical scavenging experiment and ESR results confirmed that • OH, • O 2 − , and h + active species were involved in the catalytic degradation reaction; the corresponding mechanisms were deeply investigated. This study provides a fresh approach for constructing Fe-doped Co-CP-based composite materials as photocatalysts for degradation of antibiotic contaminants.

“…Among many strategies for renewable energy conversion and its environmental impact, photoelectrochemical (PEC) water splitting based on solar- and light-driven abilities is a promising strategy that representes alternative renewable energy sources such as H 2 and other value-added products and develops clean energy. − Photocatalytic water splitting is an efficient and cost-effective strategy to convert natural solar energy into chemical energy using a semiconductor photoanode . The vast majority of visible light responsive transition of MOFs can be used as attractive scaffolds for photocatalytic water splitting.…”

Catalysts played a crucial role in advancing modern human civilization, from ancient times to the industrial revolution. Due to high cost and limited availability of traditional catalysts, there is a need to develop cost-effective, high-activity, and nonprecious metal-based electrocatalysts. Metal−organic frameworks (MOFs) have emerged as an ideal candidate for heterogeneous catalysis due to their physicochemical properties, hybrid inorganic/organic structures, uncoordinated metal sites, and accessible organic sections. MOFs are high nanoporous crystalline materials that can be used as catalysts to facilitate polymerization reactions. Their chemical and structural diversity make them effective for various reactions compared to traditional catalysts. MOFs have been applied in gas storage and separation, ion-exchange, drug delivery, luminescence, sensing, nanofilters, water purification, and catalysis. The review focuses on MOF-enabled heterogeneous catalysis for value-added compound production, including alcohol oxidation, olefin oligomerization, and polymerization reactions. MOFs offer tunable porosity, high spatial density, and single-crystal XRD control over catalyst properties. In this review, MOFs were focused on reactions of CO 2 fixation, CO 2 reduction, and photoelectrochemical water splitting. Overall, MOFs have great potential as versatile catalysts for diverse applications in the future.

“…16 Currently, heterojunction engineering is an efficient way to improve charge carriers' separation. 12,[17][18][19][20] A host Cd x Zn 1−x S semiconductor with twin-induced zinc blende/ wurtzite (ZB/WZ) crystal structure was studied and reported by Guo et al 21,22 The typical type II band structure staggered arrangement is formed between the internal ZB and WZ segments within twin Cd 0.5 Zn 0.5 S, which significantly accelerates the separation and transport of the photoinduced electronhole pairs and suppresses the recombination of charge carriers. Compared to the ordinary structure Cd 0.5 Zn 0.5 S or modified composite materials, single component twin Cd 0.5 Zn 0.5 S exhibits excellent hydrogen evolution activity.…”
