The design and synthesis of organic-inorganic hybrid composite catalysts are highly desirable in industrial applications. Many active homogeneous catalysts, particularly organometallic complexes were developed to catalyze several important organic reactions (Shelke et al., 2018, Shende et al., 2019). Nevertheless, supported catalysts are preferable due to operational simplicity, ease of separation and recyclability as well as to limit quantiti...
