Biomass‐based catalysis has drawn a gradually increased attention due to its eco‐friendliness, cost‐effective, and good reusability. In this work, a novel metal–organic framework (MOF) derived nitrogen‐doped zinc oxide carbon (ZnO/N/C) nanocomposites were synthesized on pine cone by solvothermal and carbonization method. Scanning electron microscopy, x‐ray diffractometer, and x‐ray photoelectron spectroscopy were employed to confirm the presence of N‐doped ZnO rod‐like nanostructures on the as‐prepared composites. The obtained ZnO/N/C nanocomposites were employed as catalytic materials for the decomposition of methylene blue (MB) dye and adsorption of formaldehyde (HCHO). The ZnO/N/C nanocomposites can degrade more than 90% of the MB solution within 90 min under visible light irradiation, besides, they can rapidly absorb and decompose HCHO. The high‐catalytic performance of ZnO/N/C nanocomposites can be attributed to the high‐superficial area of ZIF‐8, the carbonization that ensures the high conductivity and high‐slight absorption of carbon skeleton materials, and the accelerated transfer of photogenerated electrons. This simple and green preparation method has promoted the sustainable utilization of biomass resources with great significance for application of carbon‐based porous materials in catalytic field.Highlights MOF derived ZnO/N‐doped carbon nanocomposites were successfully synthesized. Presence of N‐doped ZnO rod‐like nanostructures on carbon nanocomposites. ZnO/N/C nanocomposites could be used as a catalyst for MB photodegradation. ZnO/N/C nanocomposites can be readily absorption and decompose of HCHO.

The production of value-added materials from waste resources is a sustainable approach for solid waste management. Facile yet economic conversion of carbon-neutral biowastes into a metal-free porous carbon material with a high oxygen reduction reaction (ORR) and capacitive energy storage efficiency is critical for renewable energy conversion and storage technologies. Herein, a microporous carbon with a self-doped N heteroatom (ALPC) was successfully prepared from waste agarwood leaves through a chemical activation process. The synthesized ALPC-800 material containing N (11.23 atom %) and O (8.54 atom %) with a high surface area as an electrocatalyst for ORR shows an onset potential (E onset ) of 0.98 V and excellent limiting current density (J L ) of 6.09 mA cm −2 , which are comparable to 10 wt % Pt/C. ALPC-800 as an electrocatalyst shows a four-electron transfer-mediated ORR process which is supported by both experimental and theoretical findings. Also, ALPC-800 in a threeelectrode configuration for supercapacitors presented a high specific capacitance of 421 F g −1 at a current density of 1 A g −1 in an acidic electrolyte. More prominently, the assembled symmetrical supercapacitor device based on ALPC-800 demonstrated a high capacitance retention of 91% after 6000 cycles at 1 A g −1 with a remarkable energy density of 21.15 Wh kg −1 and a power density of 4.93 kW kg −1 . Thus, this work provides an environmentally benign, simple, efficient, and economical method for energy storage and conversion applications. Being a metal-free catalyst, heteroatom-doped ALPC-800 carbon material synthesized from biowaste has the potential to replace the commercially available high-cost Pt/C catalyst for fuel cell application.
