This paper reports a new method of direct recovery highly pure lead oxide (PbO) from waste pastes and grids spent lead–acid batteries via catalytic conversion, desulfurization, recrystallization processes in sequence. On the basis analytical results (Pb) dioxide (PbO2) contents scrap paste, certain amount grid was used as reductant to transform excess PbO2 into sulfate (PbSO4). systematically studies influence concentration sulfuric acid (H2SO4) catalyst reaction temperature on process. The...
This study evaluated the effects of air humidity on spontaneous combustion characteristics coal. Four levels relative (dry air, 30%, 60%, and 100%) were used as experimental flow. The crossing point temperature (CPT) oxidation products measured using a self-designed system. We found CPT values 153°C, 151°C, 150°C, 148°C for four humidity, respectively. concentration production increased with an increase in humidity. Then, thermal coal studied thermogravimetric differential scanning...
The carbon supercapacitance strongly relies upon the electrolyte’s nature, but clear-cut structure–performance nexus remains elusive. Herein, a series of bio-carbons with gradually varied pore structure and surface chemistry are derived using new salt template protocol (with eco-benign KNO3 as template, activator, porogen, cheap gelatin precursor), used model systems to probe dependence electrochemical mechanism such nanocarbons on two typical electrolytes (KOH EMIBF4). By only adjusting...
Owing to the intrinsically wide bandgap and high uniformity, amorphous Ga2O3 (a-Ga2O3) has been illustrating a great industrial potential for large-area deep ultraviolet (UV) photosensor arrays. However, seemingly irreconcilable contradiction between responsivity long persistent photoconductivity hampered growing pace of such devices. In this work, three-terminal InGaZnO (IGZO)/a-Ga2O3 dual-active-layer (DAL) transistors were developed realize ability a-Ga2O3 as active layer both in...
Supercapacitors have the rapid charge/discharge kinetics and long stability in comparison with various batteries yet undergo low energy density. Theoretically, square dependence of density upon voltage reveals a fruitful but challenging engineering tenet to address this long-standing problem by keeping large window compositionally/structurally fine-tuned electrode/electrolyte systems. Inspired this, facile salt-templating enables hierarchically porous biochars for supercapacitors filled...
Carbon-based materials, as some of the most important electrode materials for supercapacitors (SC), have spurred enormous attentions. Now, it is highly desirable but remains an open challenge to design stable and high-capacity carbons further enhancing supercapacitive function. Here, a facile chemical activation recipe introduced develop biomass-derived functional using cheap abundant natural resources, anthracite, heteroatom-rich carbon sources, potassium hydroxide (KOH) activator. These...
In this study, the optimized expanded vermiculite (EVM) was used as matrix and a series of novel form-stable composite phase change materials (fs-CPCMs) were prepared by physical impregnation method. The results showed that acid leaching organic intercalation EVM had better package effect (≥74.9 wt %) heat storage capacity (≥139.2 J/g) compared with EVM, which good optimization effect, revealing proper modification treatment beneficial to improvement thermophysical properties PCMs....
