NiO with novel flower-like morphology was prepared by using a two-step, template- and surfactant-free, environmentally friendly method. Flower-like composed of many irregular nanosheets that were assembled together weak interactions. The as-prepared materials characterized X-ray diffraction, thermogravimetric analysis, differential scanning calorimetry, electron microscopy, transmission microscopy selected area diffraction patterns, N2 sorption, temperature-programmed reduction CO,...
Amorphous nanomaterials have drawn extensive attention owing to their unique features, while amorphization on noble metal still remains formidably challenging. Herein, we demonstrate a universal strategy synthesize amorphous Pd-based from unary quinary metals through the introduction of phosphorus (P). The nanoparticles (NPs) exhibit generally promoted oxygen reduction reaction (ORR) activity and durability compared with crystalline counterparts. Significantly, P-PdCuNiInSn NPs, benefiting...
The aim of this study was to investigate the effects reaction temperature on photocatalytic activity TiO2 with Pd and Cu cocatalysts. N2 sorption, transmission electron microscopy high-resolution were used characterize specific surface area, pore volume, size, morphology metal distribution catalysts. destruction methylene blue under UV light irradiation test its activity. concentration in water determined by UV-vis spectrophotometer. Pd/TiO2 catalyst more active than Cu/TiO2 TiO2. At 0–50 °C...
Ir-based heterogeneous catalysts for photocatalytic CO2 reduction have rarely been reported and are worthy of investigation. In this work, TiO2 nanosheets with a higher specific surface area more oxygen vacancies were employed to support Ir metal by impregnation (Imp) ethylene glycol (EG) methods. comparison Ir/TiO2 TiO2, exhibited excellent performance toward reduction, especially CH4 production on account the defect rich hydroxyl groups produced from interaction between metallic Ir. situ...
Abstract In the fluid catalytic cracking reactor heavy gas oil is cracked into more valuable lighter hydrocarbon products. The input a mixture of hydrocarbons which makes reaction kinetics very complicated due to involved reactions. this paper, four‐lump model proposed describe process. This different from others mainly in that deposition rate coke on catalyst can be predicted conversion and isolated C 1 – 4 yield. important since supplies heat required for endothermic reactions occurring...
A series of nanosized gold supported on CeO2, MnO2, and MnO2−CeO2 composite oxides have been prepared by a deposition−precipitation (DP) method the effects Mn/Ce atomic ratio Au/MnO2−CeO2 catalysts calcination temperature after loading for preferential oxidation CO (PROX) in H2 stream investigated using fixed-bed continuous-flow reactor at various temperatures. The were characterized XRD, nitrogen sorption, TEM, XPS. XRD analysis confirms phase purity CeO2 MnO2 phases fine dispersion Au...
Au–Ag/CeO2 catalysts with various Au/Ag atomic ratios were prepared by deposition–precipitation method. These tested for preferential oxidation of carbon monoxide (PROX). have been characterized XRD, TEM, TPR, and XPS techniques to gain the structural information on supported metal catalysts. Fine gold nanoparticles around 2–4 nm formed dispersed well support. ratio 5:5 showed higher catalytic activity than monometallic other bimetallic 9:1 7:3. The CO selectivity increased increasing silver...
Rational tailoring of the local coordination environment single atoms has demonstrated a significant impact on electronic state and catalytic performance, but development catalysts beyond noble/transition metals is profoundly highly desired. Herein, main-group metal indium (In) atom immobilized sulfur-doped porous carbon nitride nanosheets (In@CNS) in form three nitrogen coordinated with one sulfur (In-N
Cu-doped titanium dioxide thin films (Cu/TiO2) were prepared on glass substrate via peroxo sol-gel method and dip-coating process with no subsequent calcination for the degradation of organic dye use as an antibacterial agent. The as-prepared materials characterised using transmission electron microscopy (TEM), X-ray diffraction (XRD), scanning (SEM) photoelectron spectroscopy (XPS). For photocatalytic methylene blue in water, samples subjected to Ultraviolet C (UVC) visible light...
Hard carbon is the most promising anode for potassium-ion batteries (PIBs) due to its low cost and abundance, but limited storage capacity remains a major challenge. Herein, edge coordination of metal single atoms proved be an effective strategy promoting potassium in hard first time, taking B, N co-doped nanotubes anchored by Ni-N4 -B atomic sites (Ni@BNHC) as example. It revealed that can provide active interlayer adsorption K+ Ni facilitate reversibility on B atoms. Furthermore,...

Pain and itch are closely related sensations, yet qualitatively quite distinct. Despite recent advances in brain imaging techniques, identifying the differences between pain signals cortex is difficult due to continuous temporal spatial changes signals. The high resolution of positron emission tomography (PET) functional magnetic resonance (fMRI) has substantially advanced research itch, but these uncomfortable because expensiveness, importability limited operation shielded room. Here, we...
