Dwindling energy sources and a worsening environment are huge global problems, and biomass wastes are an under-exploited source of material for both energy and material generation. Herein, self-template decoction dregs of Ganoderma lucidum-derived porous carbon nanotubes (ST-DDLGCs) were synthesized via a facile and scalable strategy in response to these challenges. ST-DDLGCs exhibited a large surface area (1731.51 m2 g−1) and high pore volume (0.76 cm3 g−1), due to the interlacing tubular structures of precursors and extra-hierarchical porous structures on tube walls. In the ST-DDLGC/PMS system, the degradation efficiency of capecitabine (CAP) reached ∼97.3% within 120 min. Moreover, ST-DDLGCs displayed high catalytic activity over a wide pH range of 3–9, and strong anti-interference to these typical and ubiquitous anions in wastewater and natural water bodies (i.e., H2PO4−, NO3−, Cl− and HCO3−), in which a 1O2-dominated oxidation was identified and non-radical mechanisms were deduced. Additionally, ST-DDLGC-based coin-type symmetrical supercapacitors exhibited outstanding electrochemical performance, with specific capacitances of up to 328.1 F g−1 at 0.5 A g−1, and cycling stability of up to 98.6% after 10,000 cycles at a current density of 2 A g−1. The superior properties of ST-DDLGCs could be attributed to the unique porous tubular structure, which facilitated mass transfer and presented numerous active sites. The results highlight ST-DDLGCs as a potential candidate for constructing inexpensive and advanced environmentally functional materials and energy storage devices. |
