Adsorption equilibrium and kinetics of CO, H and CH on zeolite 13 X were carried out using the volumetric method. The zeolite 13 X was characterized via XRD, SEM and N adsorption-desorption. Adsorption isotherms of various gas were investigated over a full range of temperatures at 298, 308 and 313 K.
View Article and Find Full Text PDFLead-free double perovskites are unique materials for transport and optoelectronic applications that use clean resources to generate energy. Using first-principle computations, this study thoroughly investigates the structural, thermoelectric, and optical attributes of ATlAgF (A = Rb, Cs). Tolerance factor and formation energy estimates are used to verify that these materials exist in the cubic phase.
View Article and Find Full Text PDFThe double perovskites are become the emerging aspirant to fulfill the demand of energy. Therefore, the optoelectronic, elastic and transport characteristics of Ba XMoO (X = Zn, Cd) are addressed systemically. The elastic constants show the mechanical stability.
