Article Abstract
Fast pyrolysis of biomass has attracted increasing attention worldwide to produce bio-tars that can be upgraded into liquid fuels and chemicals. However, the bio-tars are usually poor in quality and stability and are difficult to be upgraded. To better understand the nature of the bio-tars, this work reveals radical concentration of tars derived from pyrolysis of two kinds of biomass. The tars were obtained by condensing the pyrolysis volatiles in 3s. It shows that the tars contain large amounts of radicals, at a level of 10(16)spins/g, and are able to generate more radicals at temperatures of 573K or higher, reaching a level of 10(19)spins/g at 673K in less than 30min. The radical generation in the tar samples is attributed to the formation of THF insoluble matters (coke), which also contain radicals. The radical concentrations of the aqueous liquids obtained in pyrolysis are also studied.

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.

In this work, carbon nanodots (CNDs) were synthesized via a pyrolysis carbonization method using petals. The synthesized CNDs exhibit optical absorption in the UV region, with a tail extending out into the visible range. When these CNDs interact with Ho ions through charge transfer processes, they form an RE-CNDs hybrid (Rare Earth-CNDs hybrid), resulting in fluorescence quenching in an aqueous solution.

To contribute to the circular and sustainable economy framework, waste tire rubber reclamation by extracting carbon black through pyrolysis and heat treatment and then ingeniously designing it as an electromagnetic wave absorbing (EWA) material is proposed herein. The results showed that the pyrolysis-recycled carbon black (RCB) was heterogeneous with multiple interfaces, making it suitable for EWA application. The RCB was processed at 500 °C-1000 °C to study the changes in the composite and microstructure as well as the EWA properties.
