Current Trends in Cellulose Assisted Combustion Synthesis of Catalytically Active Nanoparticles

Abstract

Cellulose assisted combustion synthesis (CACS) has emerged as a novel variation of traditional solution combustion synthesis (SCS) over the past decade for the synthesis of catalytically active nanomaterials. This report targets to summarize the fundamental developments in the synthesis technique seeking correlations between synthesis conditions, observed chemo-physical properties. Molecular level interactions among the metal precursors and reducing agents that lead to combustion reaction and thermal wave propagation in CACS are expected to be different from the SCS method due presence of cellulose fibrils affecting the thermo-physical properties and energy density of the system. In addition, the void spaces and pores may generate a complex network of micro and nanoreactors as opposed to a continuous volume of reacting species in SCS. The goal of this report is to gather the essential developments so far and provide an outlook for future directions.

Development of CuAg/Cu2O nanoparticles on carbon nitride surface for methanol oxidation and selective conversion of carbon dioxide into formate

“…One of the primary goals of catalysis research is to design catalysts that are sufficiently active and selective toward a particular desirable reaction. Catalysts long term stability, cost and scale up of synthesis processes are crucial to have any industrial relevance [1][2][3][4][5]. It is often realized that bimetallic catalysts are more suitable than the individual constituent metals for many reactions where the knowledge of surface composition, heterogeneity, and surface-reactant interactions are important in optimizing the active sites and understanding the role of individual elements in driving the reaction [2,3].…”

A review on the preparation of anode materials and anode films for solid oxide fuel cell applications

“…As a result, this modified method has a lower temperature than the conventional one 167 . This method is commonly used by researchers to synthesize nanoparticles 168 . However, the yield of nanoparticles from this method is considerably low.…”

“…167 This method is commonly used by researchers to synthesize nanoparticles. 168 However, the yield of nanoparticles from this method is considerably low. The configuration or arrangement of the cellulose can prevent the problem, which is small yielding by preventing the nanopowders to spread out during the combustion.…”

Effect of nickel on combustion synthesized copper/ fumed‐SiO 2 catalyst for selective reduction of CO 2 to CO

“…Combustion synthesis has gained a considerable research interest for catalysts preparation over the past decade due to the simplicity of the technique that requires only a few synthesis steps for preparing reasonably large amount of catalysts. [31][32][33][34][35][36][37] Primarily combustion-based techniques have been used to synthesize unsupported materials, however, more recently a shift in the direction of supported catalyst is clearly seen. [38][39][40][41][42] The choice of fumed-SiO 2 is based on some recent reports highlighting its role in achieving a high dispersion of active sites on the surface compared to other supports.…”
