Layered double hydroxide (LDH) is considered a highly promising electrode material for supercapacitors (SCs) due to its high theoretical specific capacitance. However, LDH powders often suffer from poor electrical conductivity, structure pulverization, slow charge transport, and insufficient active sites. Herein, a self‐supporting electrode with a Mott–Schottky heterostructure has been designed for high‐performance SCs. The electrode consists of low crystallinity NiCo‐LDH nanosheets and vertical graphene (VG) directly grown on carbon cloth. The LDH was converted from a metal–organic framework (MOF) by the sol–gel method. This self‐supporting electrode provides fast charge transfer, reducing the pulverization effect and energy barrier. The Mott–Schottky heterostructure of LDH@VG regulates electron density and enhances electron transfer, as confirmed by density functional theory calculation. The optimized LDH@VG heterostructure electrode exhibits an excellent areal capacitance of 5513.8 mF cm−2 and rate capability of 82.1%. Furthermore, the fabricated hybrid SC demonstrates excellent energy density of 404.8 μWh cm−2 at 1.6 mW cm−2 and a remarkable cycling life, with a capacitance of 92.0% after 10 000 cycles. This work not only provides a simple dip‐coating and MOF conversion method to synthesize heterojunction‐based electrodes, but also broadens the horizon for designing advanced electrode materials for SCs.

Bamboo has become a new trend or focus point as a source of biomass energy in which its proper application is believed to generate the electricity with near-zero waste. ASEAN countries especially have an abundant amount of bamboo that has been use for decades in various applications through their civilization. This study aims to determine the feasibility of bamboo as a renewable energy resource in Malaysia, Indonesia, Vietnam and Japan. This paper reviews general biomass bamboo, availability, and methods of technology in the respective countries based on the review of publication papers and country reports. This fast-growing crop is identical for biomass production as it rapidly self-propagates. Bamboo requires minimum maintenance to grow and is always accessible to be harvested. The woody nature of the tropical bamboo stem contributes to its high calorific value in the form of energy. It was found that Indonesia had become a leading country in generating renewable energy via biomass bamboo through a power plant with a capacity of 700 kW off-grid in Mentawai, Japan with a power generation capacity of 995 kW and Malaysia with 4 MW, will be commercialised by 2023 and 2022. In conclusion, biomass bamboo has great potential for renewable energy generation within these countries. This has consequently contributed to increase in the value of bamboos while positively impacting the socioeconomic stance of the community. [ABSTRACT FROM AUTHOR]
