Article Abstract
Catalytic pyrolysis of rain tree biomass (RTB), a typical horticultural waste, was investigated with nano-NiO as catalyst produced from hazardous nickel plating slag (NPS). It appeared from the analyses by FTIR, TGA, XRD, BET, and FESEM/EDX that nano-NiO produced had a S and mean particle size of 53.4 m/g and 112.3 nm. The catalytic pyrolysis kinetics of RTB with and without catalyst were studied by Friedman method. It was found that the activation energy (E) was in the range of 177 to 360 kJ/mol at a conversion rate of 0.1 - 0.75. The results further revealed that the H increase ratio in pyrolysis above 500 °C was more than 40% in the presence of catalyst. Consequently, this study showed the great potential of nano-NiO as a high-efficiency catalyst in recovering energy from biomass.

Metal-nitrogen-carbon (M-N-C) catalysts display considerable potential as cost-effective alternatives to noble metals in oxygen electrocatalysis. However, uncontrolled atomic migration and random structural rearrangement during pyrolysis often lead to disordered coordination environments and sparse active sites, fundamentally limiting their intrinsic catalytic activities and long-term durability. Herein, a novel strategy is reported for use in directionally regulating atomic migration pathways via the incorporation of a foreign metal (La).

The synthesis of biomass-derived nanocarbons via ball milling has emerged as an innovative, sustainable, and cost-effective strategy in the field of nanotechnology. This review comprehensively explores the principles, mechanisms, and process parameters that influence the production of high-quality nanocarbons from biomass using ball milling. This process efficiently transforms biomass residues into nanoscale carbon, including graphene, carbon nanotubes, and nanofibers, with tunable physicochemical properties tailored for advanced applications.

Herein, a novel S/N co-doped carbon-based nanozyme （S/N-Fe） with peroxidase-like properties was synthesized by doping thiourea into Fe MOF and introducing g-CN for pyrolysis. Generated by enzymatic cascade with acetylcholinesterase (AChE) involved, HO could react with S/N-Fe to generate reactive oxygen species (ROS). O-Phenylenediamine (OPD) could be catalyzed by ROS, resulting in the production of 2,3-diaminophenazine (DAP) with a fluorescent emission at 564 nm.

The rapid increase of electronic waste, particularly battery waste, presents significant environmental challenges such as pollutant emissions and resource depletion, emphasizing the need for effective valorization and reuse strategies. This study introduces a novel approach for repurposing end-of-life lithium iron phosphate (LFP) batteries as catalysts in the pyrolysis of walnut shells (WS). Characterization analyses revealed that LFP provides both Lewis and Brønsted acid sites, which alter the thermal decomposition pathway of WS.
