This work aimed to investigate the effect of pyrolysis temperature on yield and properties biochars synthesized from herbaceous woody plants. Four typical materials, including two plants (rice straw, corn straw) (camellia oleifera shells, garden waste), were used in experiments under five operating temperatures (from 300 °C 700 °C, with an interval 100 °C). The results showed biochar derived had a significantly higher pH 7.68 11.29 for RS), electrical conductivity (EC, 6.5 Ms cm
The role of modified biochar in enhancing phosphorus (P) availability is gaining attention as an environmentally friendly approach to address soil P deficiency, a global agricultural challenge. Traditional phosphatic fertilizers, while essential for crop yield, are costly and detrimental owing fixation leaching. Modified presents promising alternative with improved properties such increased porosity, surface area, cation exchange capacity. This review delves into the variability based on...
Nitrogen-doped activated carbon sheets were derived from chitin, which exhibited remarkable activity for ORR and high catalytic towards OER.
Heteroatom-doped lamellar-structured carbon with a high surface area synthesized from alfalfa leaves is utilized as cathode catalyst in this study to improve the power output of microbial fuel cells (MFCs). Different chemical activation agents are used treat leaf-derived (ALC). It found that substantially affect catalytic activities materials MFCs and oxygen reduction reaction (ORR). ALC activated by KOH (ALC-K) exhibit best electrochemical activity compared those FeCl3 (ALC-Fe) or ZnCl2...
Naturally abundant pomelo peels were explored for the preparation of metal-free carbon-based microspheres with high electrocatalytic activity and long-term durability toward ORR, holding potential replacing noble metal-based catalysts.
Nonactivated and activated biochars have been successfully prepared by bananas at different thermotreatment temperatures. The biochar generated 900°C (Biochar-act900) exhibited improved oxygen reduction reaction (ORR) evolution (OER) performances in alkaline media, terms of the onset potential current density. Rotating disk electron result shows that average 2.65 electrons per molecule was transferred during ORR Biochar-act900. highest power density 528.2 mW/m 2 maximum stable voltage 0.47 V...
Abstract Efficient, low‐cost electrocatalysts for the oxygen reduction reaction are essential components of renewable energy technologies. Herein, hierarchical multiwalled MnO 2 /polypyrrole/MnO nanotubes (NT‐MPMs) were synthesized by using a simple, cost‐effective hydrothermal method. The key to fabricating NT‐MPMs was introduce conductive polypyrrole (PPy) interlayer improve electrical conductivity nanotubes. In alkaline media, these rationally designed exhibited remarkable...
Abstract Biochar modified by metal ions—particularly Mg—is typically used for the effective recovery of phosphorous. In this study, MgO-modified biochars were synthesized via direct co-pyrolysis MgO and raw materials such as rice straw, corn Camellia oleifera shells, branches from garden waste, which labeled MRS, MCS, MOT, MGW, respectively. The resulting phosphate (PO) adsorption capacities potential mechanisms analyzed. PO significantly improved after modification with MgO: MRS (24.71 ±...
As a notorious hazardous waste, biomass tar has for long time been recognized as one of the key challenges throughout progress in gasification renewable energy and chemical purposes. In this contribution, we report that featured with considerably high carbon nitrogen contents could serve an ideal source production nitrogen-doped highly ultramicroporous following facile activation approach, which enabled remarkably ultramicroporosity based on direct bottom-up strategy. Further, disclosed...
