In recent years, Pillared InterLayered Clays (PILCs) have been widely used in several applications; in particular in adsorption and catalysis. The research interest in this family of solids has increased considerably. Clay minerals provide distinct nanometer-scaled layers and interlayers for engineering them as active catalysts. As such, strategic design and preparation has led to a variety of ...

Abstract Catalysts are involved in a number of established and emerging chemical processes as well environmental remediation energy conversion. Nanoparticles (NPs) can offer several advantages over some conventional catalysts, such higher efficiency selectivity. Nowadays, versatile scalable nanocatalysts that combine activity stability still lacking. Here, we report comprehensive investigation ...

Molecular surface functionalization of metallic catalysts is emerging as an ever-developing approach to tuning their catalytic performance. Here, we report the synthesis hybrid comprising copper nanocrystals (CuNCs) and imidazolium ligand for electrochemical CO2 reduction reaction (CO2RR). We show that this organic modifier steers selectivity cubic CuNCs toward liquid products. A comparison bet...

This paper reviews various types of heterogeneous acid-base catalysts for fragrances preparation. Catalytic activities of the various types of heterogeneous acid and base catalysts in fragrances preparation, i.e. nonzeolitic, zeolitic, and mesoporous molecular sieves, have been reported. Generally, heterogeneous acid catalysts are more commonly used in fragrance synthesis as compared to heterog...

A novel clay (aminoclay, AC) functionalized multi-walled carbon nanotube (MWCNT) was employed as a hybrid supporting material to Ag and Au nanoparticles for the improvement of oxygen reduction reaction (ORR). The size structure catalysts were studied by XRD electron microscopy analysis, revealing that average crystallite particle about 3.4 2.6 nm 16.2 15.3 nanoparticles, respectively. ORR perfo...

The performance of 23 density functionals, including one LDA, four GGAs, three meta-GGAs, three hybrid GGAs, eight hybrid meta-GGAs, and ten double-hybrid functionals, was investigated for the computation of activation energies of various covalent main-group single bonds by four catalysts: Pd, PdCl(-), PdCl2, and Ni (all in the singlet state). A reactant complex, the barrier, and reaction energ...

Catalysts for the oxidation of H2O are an integral component of solar energy to fuel conversion technologies. Although catalysts based on scarce and precious metals have been recognized as efficient catalysts for H2O oxidation, catalysts composed of inexpensive and earth-abundant element(s) are essential for realizing economically viable energy conversion technologies. This Perspective summariz...

The epoxidation reaction using heterogeneous solid catalysts with H2O2 as oxidants are environmentally friendly routes to produce extensively useful epoxides which are traditionally obtained from capital-intensive or environmentally polluted processes. In this paper, various types of solid catalysts for the epoxidation of olefins with H2O2 as oxidants are reviewed. The efficient catalysts repor...

This review examines recent advances in photocatalytic CO2 reduction using heterogenized molecular catalysts. The main part of the discussion is focused on chemistry used to attach catalysts different supports produce hybrid materials, and how this effects performance. Examples materials for colloidal dispersions solid suspensions are presented, including those based carbon nitride, chalcogenid...

The heterogenization of homogeneous catalysts onto a solid support is step towards more sustainable chemistry. recovery and reuse extremely important from practical, economic environmental point view. In this regards, we report series polymer-supported tetrahydropyran-based hybrid dipeptides that serve as active for the enantioselective Michael addition aldehydes to β-nitrostyrenes. These suppo...
