Fabricating electronic devices from natural, renewable resources is a common goal in engineering and materials science. In this regard, carbon is of special significance due to its biocompatibility combined with electrical conductivity and electrochemical stability. In microelectronics, however, carbon's device application is often inhibited by tedious and expensive preparation processes and a lack of control over processing and material parameters. Laser‐assisted carbonization is emerging as a tool for the precise and selective synthesis of functional carbon‐based materials for flexible device applications. In contrast to conventional carbonization via in‐furnace pyrolysis, laser‐carbonization is induced photo‐thermally and occurs on the time‐scale of milliseconds. By careful selection of the precursors and process parameters, the properties of this so‐called laser‐patterned carbon (LP‐C) such as porosity, surface polarity, functional groups, degree of graphitization, charge‐carrier structure, etc. can be tuned. In this critical review, a common perspective is generated on laser‐carbonization in the context of general carbonization strategies, fundamentals of laser‐induced materials processing, and flexible electronic applications, like electrodes for sensors, electrocatalysts, energy storage, or antennas. An attempt is made to have equal emphasis on material processing and application aspects such that this emerging technology can be optimally positioned in the broader context of carbon‐based microfabrication.

“…The graphitized carbon structure after pyrolysis improves resistance, mechanical stability, and precursor substrate adhesion. [ 300 , 301 ] When using poly(1,1‐difluoroethylene) (PDFE) as a precursor for localized laser heating, the incorporation of MXene contributes to fiber reinforcement and heat transfer. During pyrolysis, MXene lowers the carbonization temperature and forms microstructures along the fibers while accelerating the transformation of the graphitic structure of the carbon material.…”

The shortage and unevenness of fossil energy sources are affecting the development and progress of human civilization. The technology of efficiently converting material resources into energy for utilization and storage is attracting the attention of researchers. Environmentally friendly biomass materials are a treasure to drive the development of new‐generation energy sources. Electrochemical theory is used to efficiently convert the chemical energy of chemical substances into electrical energy. In recent years, significant progress has been made in the development of green and economical electrocatalysts for oxygen reduction reaction (ORR). Although many reviews have been reported around the application of biomass‐derived catalytically active carbon (CAC) catalysts in ORR, these reviews have only selected a single/partial topic (including synthesis and preparation of catalysts from different sources, structural optimization, or performance enhancement methods based on CAC catalysts, and application of biomass‐derived CACs) for discussion. There is no review that systematically addresses the latest progress in the synthesis, performance enhancement, and applications related to biomass‐derived CAC‐based oxygen reduction electrocatalysts synchronously. This review fills the gap by providing a timely and comprehensive review and summary from the following sections: the exposition of the basic catalytic principles of ORR, the summary of the chemical composition and structural properties of various types of biomass, the analysis of traditional and the latest popular biomass‐derived CAC synthesis methods and optimization strategies, and the summary of the practical applications of biomass‐derived CAC‐based oxidative reduction electrocatalysts. This review provides a comprehensive summary of the latest advances to provide research directions and design ideas for the development of catalyst synthesis/optimization and contributes to the industrialization of biomass‐derived CAC electrocatalysis and electric energy storage.
