Design and development of a highly efficient reusable zeolite impregnated ZnAlO catalyst for biodiesel production.

As the demand for sustainable energy sources expands, the production of biodiesel has attracted great attention. The development of effective and ecologically friendly biodiesel catalysts has become an urgent need. In this context, the goal of this study is to develop a composite solid catalyst with enhanced efficiency, reusability, and reduced environmental impact.

Synthesis, Experimental, and Theoretical Study of Co Ni O Mixed Oxides: Potential Candidates for Hydrogen Production via Solar Redox Cycles.

Recently, green hydrogen production via solar thermochemical water splitting (STWS) as a clean and sustainable method is becoming a subject of interest to many researchers. Great efforts are being made to develop materials for STWS with suitable operating conditions, low cost, and good cycling stability. In this context, the study of mixed cobalt and nickel oxides with the general formula Co Ni O (0 ≤ ≤ 1) was carried out, where four mixed metal oxides CoNiO, CoNiO, CoNiO, and CoNiO have been successfully synthesized through the sol-gel method modified Pechini route.
