In this research, the surface hydrophobicity of a mesoporous molecular sieve synthesized from rice husk silica, called

Sorption Kinetics and Sequential Adsorption Analysis of Volatile Organic Compounds on Mesoporous Silica

“…Understanding adsorption of VOCs can help with designing materials for separation, and a recent study showed the potential of silica as a separation material for VOC mixtures using dynamic adsorption. ,− Moreover, most studies provide the adsorption capacity for VOCs but not the kinetics. , Understanding the temperature-dependent surface dynamics of nanoporous silica materials requires further study. The literature also lacks information about the equilibrium and sorption kinetics at different temperatures, which is expected to be adsorbate/adsorbent-dependent, as well as studies of sequential adsorption of VOCs onto porous materials.…”

Gas phase Catalytic Oxidation of VOCS using Hydrothermally Synthesized Nest-like K-OMS 2 Catalyst

“…Several studies showed the efficiency of non-thermal plasma catalysis (Guo et al 2006), condensation, membrane separation, biofiltration (Quoc An et al 2011;Zhao et al 2011), adsorption (Areerob et al 2015;Yakout & Daifullah 2014;Yang et al 2013), photocatalysis (Luo et al 2006;Momani & Jarrah 2009) and catalytic oxidation (Jothiramalingam & Wang 2007;Santos et al 2010) in the decomposition of VOCs present in the atmosphere. Though some processes are found to be effective, the ease of performing the process and the means of producing its precursors must also be taken into consideration.…”
