Black liquor is hazardous and one of the main byproducts in the pulp and paper industry. Its primary constituent is lignin, a carbonbased molecule serving as a precursor for the synthesis of nanostructured carbon materials. Herein, we have used black liquor as a precursor to synthesize high surface area carbons for use as electrochemical oxygen reduction reaction (ORR) catalysts. The materials were activated by a NaOH treatment and subsequently nitrogen-doped by mixing with dicyandiamide, followed by pyrolysis. Synthesis resulted in catalyst materials that showed high specific surface area (1807 and 1228 m 2 g −1 , respectively), high surface nitrogen content (6.7 and 5.1 at. %, respectively), and the inclusion of chromium and sulfur impurities that originated from the black liquor. The black liquor-based catalyst exhibited high ORR activity in alkaline media with a half-wave potential (E 1/2 ) of 780 mV and an onset potential (E onset ) of 900 mV versus RHE. The resultant Zn−air battery delivered a high peak power density of 112 mW cm −2 at 171 mA cm −2 and a specific capacity of 633 mAh g −1 .

Lignocellulose‐mediated liquid metal (LM) composites, as emerging functional materials, show tremendous potential for a variety of applications. The abundant hydroxyl, carboxyl, and other polar groups in lignocellulose facilitate the formation of strong chemical bonds with LM surfaces, enhancing wettability and adhesion for improved interface compatibility. Beyond serving as a supportive matrix, lignocellulose can be tailored to optimize the microstructure of the composites, adapting them for diverse applications. This review comprehensively summarizes the fundamental principles and recent advancements in lignocellulose‐mediated LM composites, highlighting the advantages of lignocellulose in composite fabrication, including facile synthesis, versatile interactions, and inherent functionalities. Key modulation strategies for LMs and innovative synthesis methods for functionalized lignocellulose composites are discussed. Furthermore, the roles and structure–performance relationships of these composites in electromagnetic shielding, flexible sensors, and energy storage devices are systematically summarized. Finally, the obstacles and prospective advancements pertaining to lignocellulose‐mediated LM composites are thoroughly scrutinized and deliberated upon. This review is expected to provide basic guidance for researchers to boost the popularity of LMs in diverse applications and provide useful references for design strategies of state‐of‐the‐art LMs.

Flexible sensors exhibit the properties of excellent shape adaptability and deformation ability, which have been applied for environmental monitoring, medical diagnostics, food safety, smart systems, and human–computer interaction. Cellulose‐based hydrogels are ideal materials for the fabrication of flexible sensors due to their unique three‐dimensional structure, renewability, ease of processing, biodegradability, modifiability, and good mechanical properties. This paper comprehensively reviews recent advances of cellulose‐based hydrogels in the construction of flexible sensor applications. The characteristics, mechanisms, and advantages of cellulose‐based hydrogels prepared by physical cross‐linking, chemical cross‐linking are respectively analyzed and summarized in detail. The focus then turns to the research and development in cellulose‐based hydrogel sensors, including physical sensing (pressure/strain, humidity/temperature, and optical sensing), chemical sensing (chromium, copper, and mercury ion sensing, toxic gas sensing, nitrite sensing), and biosensing (glucose, antibody, and cellular sensing). Additionally, the limitations of cellulose‐based hydrogels in sensors, along with key challenges and future directions, are discussed. It is anticipated that this review will furnish invaluable insight for the advancement of novel green, flexible sensors and facilitate the integration of cellulose‐based hydrogels as a fundamental component in the development of multifunctional sensing technologies, thereby expediting the design of innovative materials in the near future.
