Molybdenum-loaded 1,5-diaminonaphthalene/ZnO materials with improved electrical properties and affinity towards hydrogen at ambient conditions

Metal-inorganic-organic core–shell material as efficient matrices for CO2 adsorption: Synthesis, properties and kinetic studies

“…This became the main objective of the present paper. Metal oxides, and more particularly zinc oxide (ZnO) are also assumed to exhibit interesting surface properties as adsorbent [29,30] and electronic material [31] . ZnO combination with a diethanolamine-modified cocoa shell-deriving hydrochar already showed interesting surface properties [32][33][34][35] .…”

“…When necessary, complete regeneration for a total CO 2 release from the adsorbents was achieved by slight heating up to 80 °C or by forced convection under strong air stream (15-30 mL/min) until no CO 2 was detected by bubbling into a 0.1 N aqueous NaOH solution. The adsorbent affinity towards CO 2 was examined in terms of contact time and adsorption kinetics using pseudo 1st and 2nd order models [30,38,39] .…”

“…Attempts to apply the pseudo 1st and 2nd order models [30,67] showed that CO 2 capture on HC obeys a pseudo-first order kinetics ( Fig. 7 ).…”

“…Deeper insights in CO 2 adsorption kinetics were achieved by applying the intraparticle diffusion (ID) model ( Eq. (1 )) that correlates the kinetics constant (k ID ) to the intraparticle diffusion constant (CI) [30] :…”

Polymers and TiO2 Based Nanocharges for Bio-Based Composites with Improved Flame Retardancy and Thermal Degradation

“…Abed, et al have found that adding ZnO and SiO 2 accelerates the carbonization of chlorinated poly (vinyl chloride) microfibers [8]. Metallic oxide were activated and modified by the addition of some active agent such as amine derivate for enhancing electrical and sensing properties or polyvinylidene fluoride (PVDF) to increase the surface area and the adsorption properties [8][9][10][11][12][13]. Due to their excellent flame retardancy, chemical and ecofriendly properties, polyvinylidene fluoride were widely used various applications such as the microfiltration and in advanced water separation and environmental remediation processes.…”
