MOF‐derived porous NiO with hierarchical structure (MHNiO) was prepared based on thermolysis of Ni metal organic framework (Ni‐MOF), which was used as carrier for the immobilization of horseradish peroxidase (HRP) and cytochrome C (Cyt c). The pore size of MHNiO was tuned as 11.8 nm to match the size of free enzyme so as to depress the aggregation of the enzymes in the pore. Meanwhile, the hierarchical structure allowed the substrates concentrated in the vicinity of the enzymes. The obtained enzymatic reactors exhibited better thermal stability, storage stability and reusability. For example, over 83 % of its original activity after 1 h incubation at 70 °C could be remained compared to 18.1 % or 38.4 % remained activity of free HRP and Cyt c, respectively; After 12 cycles of use, over 53 % of original catalytic activity of both the enzymatic reactor could be maintain. The enzymatic kinetic data (Km, Vmax, kcat) and thermodynamic data (Ka, ΔH, ΔS and ΔG) indicated that the improved catalytic performance was attributed to the affinity, selectivity and binding of enzyme to substrate. The two enzymatic reactors could be applied in the fast degradation of 2,4‐dichlorophenol and rifaximin in artificial wastewater, a complete degradation of 2 mg ⋅ mL−1 of 2,4‐dichlorophenol or 20 μg ⋅ mL−1 of rifaximin was achieved in only 20 min.

Globally many techniques are well developed and documented for the research in every stream as engineering, sciences, medicine, pharmaceutical and synthesis of metal nanoparticles. Some of the techniques like nanotechnology, biotechnology and biosynthesis of nanoparticles should be developed in the environmentally friendly technique in the material synthesis [1]. During recent years, AgNPs have been growing fast due to the unique characteristics and importance in antibacterial, biological, catalytic, chemical, electronic, electrochemical, optical and photo-magnetic properties [2]. The silver and gold NPs attracted researchers because of their unique applications in field like agriculture, drug delivery systems, food sectors, biomedical field, textile units and water treatment [3,4]. The use of microorganisms as antimicrobial, antifungal agent and as a catalyst for synthesis of nanoparticles and nanometals were explored. Sastry and Co-workers studied about the use of plant materials and microbes as nanofactories [5-7]. Synthesis of nanoparticles obtained by chemical and physical methods are environment friendly. This also includes design development by renewable high energy efficient nanomaterials. The biological method developed for We thankful to the Aligarh Muslim University for their support in carrying out in this research work regarding SEM-EDAX, and TEM analysis and thanks to Banaras Hindu University for their help of FT-IR spectrum analysis.

“…Moreover, the metal suldes act as the photosensitizers which can generate the more number of electrons by absorbing the visible light and easily transfer to the heterostructured materials. 20,21 Among them, CuS and CdS semiconductor chalcogenides has been considered as a simple and yet powerful photocatalyst for the degradation of organic molecules mixed in the wastewater. [22][23][24] These metal suldes have ideal electronic band structure, more number of catalytic active sites, and sufficient visible region bandgap.…”
