In this study, a simple hydrothermal approach is employed for the rational manufacturing of MoS2 nanoflowers (MoS2-NFs) grafted onto highly porous functionalized woody pulp-derived biochar (f-WPB) for use in supercapacitors (SCs). Investigations are conducted into the produced materials’ morphological, textural, physicochemical surface, and electrochemical performance. The MoS2-NFs are uniformly grown on the f-WPB and subsequently […]

The application of biomass-based sources for energy generation has attracted much interest in recent times due to their environmental benefits. In this study, the potential use of rubber seed shells and eggshells in the synthesis of bi-functional catalysts for biodiesel production has been investigated. The catalyst was produced in a sequence of steps that included […]

Redundant CO2 produced during wet anaerobic digestion (AD) needs proper in-situ minimization, in which the amino groups in polyethyleneimine (PEI) can react with CO2 to form bicarbonate by diffusing into the liquid phase. Hence, the addition of PEI-grafted material may provide a novel way to in-situ supplement bicarbonate in the AD system, which could further […]

This report presents a novel system combining microcurrent-coupled magnetic layered double hydroxide and biochar to enhance the anaerobic degradation performance of highly-concentrated phenolic wastewater. The coupled system achieves removal efficiencies for COD and 2,4,6-trichlorophenol (2,4,6-TCP) of 71.1 % and 75.40 %, respectively, which are 2.25 and 2.50 times higher than those achieved by raw sludge. […]

The thermochemical utilization of biomass char is vital for addressing environmental pollution and the energy crisis. The carbonaceous structure plays a crucial role in this process, and understanding the conversion mechanism aids in optimizing biomass reactors. This study performs a comprehensive analysis of hightemperature rice husk char using 13C NMR, XPS, and FTIR techniques. The […]

In the present study, biochar pellets and wood vinegar are prepared from the cotton stalk (CS) through the densification and pyrolysis, and hydrothermal oxidative (HO) pretreatment (160-260 degrees C) is conducted to CS to upgrade the quality of biochar pellet and wood vinegar (WV). The results show that HO pretreatment can decompose the hemicellulose, amorphous […]

The current study focuses on the capability of microalgae biochar as fuel pellets. Additionally, the study aims to investigate the treatment of synthetic saline wastewater through microalgae cultivation, which is an essential tool for meeting the sustainable environment requirements of nations. Microalgae have the tendency to absorb harmful pollutants from wastewater and use them as […]

The current study focuses on synthesizing a cost-effective high proton conductive and low oxygen crossover proton exchange membrane. The membrane is prepared using modified biochar from chili stalk waste in a sulfonated polyether sulfone polymer for microbial fuel cell applications for tamarind wastewater treatment. The membrane shows desired modification confirmed through instrumental characterization using FTIR, […]

This study showed the effects of prepared chicken bone-derived biochar (CB) and magnetic chicken bone-derived biochar (MCB) at various ratio (2-12 g/L) on anaerobic co-digestion (AcoD) of corn straw (CS) and cow dung (CD). The physiochemical characterization of CB, MCB, and lignocellulosic biomass (including CS and CD) was analyzed. Biogas production, kinetics, total solid (TS), […]
