SnTe, a lead-free rock-salt analogue of PbTe, having valence band structure similar to recently has attracted attention for thermoelectric heat electricity generation. However, pristine SnTe is poor material because very high hole concentration resulting from intrinsic Sn vacancies, which give rise low Seebeck coefficient and electrical thermal conductivity. In this report, we show that can be optimized performance power generation by controlling the significantly improving coefficient. Mg...
Understanding the basis of electronic transport and developing ideas to improve thermoelectric power factor are essential for production efficient materials. Here, we report a significantly large ∼31.4 μW/cm·K2 at 856 K in Ag In co-doped SnTe (i.e., SnAgxInxTe1+2x). This is highest so far reported SnTe-based material, which arises from synergistic effects on structure improved electrical properties SnTe. play different but complementary roles modifying valence band In-doping introduces...
In the pursuit of sustainable energy and environmental solutions, photocatalysis has emerged as a transformative technology, harnessing power light to drive chemical transformations. Among myriad photocatalytic materials, calcium titanate (CaTiO3) stands out promising candidate, holding potential revolutionize landscape photocatalysis. To further improvise efficiency CaTiO3 in this work, porous graphene-CaTiO3 nanocomposite was synthesized by straightforward solvothermal method its activity...
Complementary and beneficial effects of Sb Bi codoping in GeTe are shown to generate high thermoelectric figure merit, zT, 1.8 at 725 K Ge1-x-yBixSbyTe samples. facilitates the valence band convergence enhancing Seebeck coefficient as supported by density functional theoretical (DFT) calculations. Further, releases rhombohedral strain increases its tendency be cubic structure, which ultimately enhances degeneracy. At same time, forms nanoprecipitates size ∼5–20 nm matrix doping solid...
It is well agreed that supercapacitors form an important class of energy storage devices catering to a variety needs. However, designing the same using eco-friendly and earth abundant materials with high performance still dire need day. Here, we report facile solvothermal synthesis porous graphene-NiFe

Porous graphene-SrTiO3 (PGST) composite prepared by a facile solvothermal method was tested for its photocatalytic activity in degradation of methylene blue (MB) dye. First-principles density functional theory calculations were also carried out to study the effect nanocomposite formation on electronic structure and states. The combined experimental theoretical gave insights regarding Sr–C bond which enhanced charge transport, effectively separating carriers reduced their recombination rate....
