Solid-base catalysts have acquired significant attention due to their essential
role in various chemical processes, including catalytic transformations, environmental
remediation, and energy conversion. This chapter highlights a comprehensive overview
of current approaches to the synthesis, characterization, innovative methods, and
techniques employed in the development of solid-base catalysts. A wide array of
methodologies has emerged, ranging from traditional techniques to cutting-edge
approaches, facilitating the design and optimization of solid-base catalysts. The
synthesis section discusses novel approaches such as sol-gel hydrothermal,
nanoparticle immobilization, impregnation, metal-organic framework, fly ash
technique, template-assisted techniques, and conventional methods like generation of
the basic site by pretreatment at high temperature. Each technique offers unique
advantages in controlling catalyst morphology, composition, and surface properties.
Furthermore, recent developments in characterization techniques like X-ray diffraction,
Fourier-transform infrared spectroscopic, NMR, Temperature programmed desorption,
microscopic and surface analysis methods such as indicator method, etc., have enabled
detailed insights into the physicochemical properties and active sites of catalysts and
structure-activity relationships governing the catalytic performance of solid-base
materials. Moreover, computational methods play an essential role in predicting and
optimizing the catalytic performance of these materials. By summarizing these recent
methodologies, this chapter aims to provide valuable insights into the advancements in
solid-base catalyst development, paving the way for enhanced catalytic efficiency and
sustainability in various chemical processes.
