Abstract null null In this study, tungsten oxide (WO3) film was used to enhance the stability as well as the performance of electrochromic window (ECW) based on famous conductive polymer-polyaniline (PANI). PANI and WO3 films were prepared and employed to fabricate hybrid ECW with an unprecedented stability (over 1000 cycles) and more colorful device with various color (green, blue, and violet of neat PANI, and deep blue of WO3). The multicolor nature of device maybe due to the simultaneous chan...

Abstract null null Solar-driven splitting of water to hydrogen production is one of the utmost auspicious and cost-effective technologies providing sustainable fuel as it necessitates only sunlight and water. This substantial technology can be achieved in a two step-photoexcitation system using an artificial Z-scheme process. The key to comprehend this reaction is to discover an effective and robust photocatalyst which preferably makes sufficient use of solar energy. Benefiting from the ultrahig...

Abstract null null Solar-driven CO2-to-fuels production through photocatalysis is a promising approach to address the worsening energy crisis and environmental concerns associated with CO2 emissions. A significant effort has been devoted to developing robust photocatalytic materials to convert CO2 into fuels. However, the performances of obtained materials are still far from the desirable targets rooted in the restriction of the employed catalysts such as inefficient light-harvesting, poor charg...

Abstract null null Photocatalysis is considered to be one of the preeminent routes to realize sustainable O2 and H2 evolution, as well as CO2 reduction. Owing to various limitations, i.e. insufficient surface area, active sites, charge isolation, high overpotential, etc. associated with a single photoactive semiconductor, it is challenging to convert adsorbed H2O and CO2 to CO, H2, CH4, CH3OH, O2, etc. by harvesting solar light. Among popular cocatalysts, earth-abundant cocatalysts exhibited gre...

Abstract Transferable 2-dimensional (2D) MoS2 thin films have a versatile potential for constructing highly efficient photoelectrodes when combined with conventional semiconductor light absorbers, taking advantage of its optical transparency and high electrochemical activity. Here, we firstly report fully vertically aligned MoS2 (VMS)/p-Si heterostructure photocathode for photoelectrochemical (PEC) water splitting. Furthermore, 3D iron-nickel sulfide nanoparticles of tailored atomic composition ...

Abstract null null Anionic Congo red dye (CR) is not effectively removed by conventional adsorbents. Three novel biochars derived from agro-waste (Acacia auriculiformis), modified with metal salts of FeCl3, AlCl3, and CaCl2 at 500 °C pyrolysis have been developed to enhance CR treatment. These biochars revealed significant differences in effluents compared to BC, which satisfied initial research expectations (P

Abstract LiCoO2 is one of the most successfully commercialized cathode materials for battery applications, owing to its excellent capacity and cycle performance. LiCoO2 exhibits two main crystallographic structures depending on the calcination temperature: low-temperature cubic spinel (Fd3m) structure, often called LT-LiCoO2, and high-temperature hexagonal layered structure (R3 ¯m), referred to as HT-LiCoO2. HT-LiCoO2, which generally requires a high processing temperature, shows a better batter...

Abstract This study aims at identifying the structure of polysaccharide (PS) extracted from the biomass of Vietnam-grown Ophiocordyceps sobolifera for the first time. The molecular weight of the obtained polysaccharide (denoted as PS-T100) is found to be 2.29 × 105 Da using gel permeation high-performance liquid chromatography. The structural investigations of the sample PS-T100 unveil a novel structure composed of a heteropolysaccharide with the appearance of two main sugars, D-glucose and D-ma...
