The urgent need for eco-friendly and sustainable energy storage systems or green energy production methods to combat the detrimental effects of non-renewable fossil fuels is widely recognized. In this context, we have synthesized a pyromellitic diimide and triazine-containing covalent organic framework named PDT-COF and investigated its performance in two key energy applications: electrocatalytic hydrogen evolution reaction (HER) for green hydrogen energy production and electrochemical energy storage for supercapacitor devices. The PDT-COF nanosheets exhibit a high surface area of 312.6 m 2 /g and abundant pores with a size of ∼1.8 nm. Leveraging these features, the metal-free PDT-COF electrocatalyst demonstrates good performance in HER, requiring a minimal overpotential of 210 mV for 10 mA/cm 2 current density. Notably, PDT-COF follows the Heyrovsky−Volmer mechanism for HER and exhibits outstanding durability, sustaining over 60 h of continuous electrocatalysis. Furthermore, the PDT-COF-based asymmetric solid-state device exhibits a specific capacitance of 104 F/g, coupled with a high energy density of 32.55 W h/kg and a power density of 1875 W/kg at a current density of 1 A/g. Importantly, the robustness and cycle stability of the PDT-COF-based asymmetric pseudocapacitor device are confirmed, as it retains 88% of its initial capacitance and maintains a Columbic efficiency of 90% even after 5000 cycles of charge and discharge. Considering these findings, the synthesized PDT-COF material holds great promise as a metal-free electrode material for future applications in hydrogen energy generation and electrochemical energy storage devices.

Waste management is an activity to manage residues, by-products, and used items. Handling used cell phones is one form of waste management activity. In developing countries, used cell phones are mostly handled by informal actors, where second-hand market actors for cell phones act as collection points. Some of these activities often affect the environment and the actors' health due to a lack of adequate technology. Hence, a collaboration between informal and formal actors is necessary to handle the used cell phones and reduce the adverse effects. However, several obstacles faced by informal actors can hinder such collaboration. This study explores the inhibiting factors for the collaboration between the informal and formal actors in handling used cell phones. The respondents were 424 informal actors in five areas of the Special Region of Yogyakarta (DIY Province), Indonesia. The results showed that the unavailability of infrastructure and insufficient organization significantly hindered collaboration in the Yogyakarta municipal area. As for the areas of Gunungkidul, Bantul, Kulonprogo, and Sleman regions, there were no significant factors hindering the collaboration. The results of this study can contribute for stakeholders’ consideration related to e-waste handling, primarily used cell phones in Indonesia; thus, the management of used cell phones is safe for the environment and provide economic benefits for the informal actors.

“…As per the announcement of 2019, the government also aimed on adding 4 GW of rooftop solar capacity in a residential area by 2019–2020 but only 1.31 GW capacity was achieved until 2021 per the ministry. The Prime Minister has announced a National Hydrogen Mission which aims for increasing self‐reliance and enabling clean energy transition 40 . The mission target is to scale up the production of hydrogen using renewable sources instead of conventional processes.…”

The COVID‐19 pandemic presented a chance to investigate the effects of system‐wide emergencies on major global commodities such as water and energy. In terms of environmental policies and attaining supply security, these developmental goals are interrelated. Despite pandemic disruptions, there is a compelling need for a systematization in these areas for the transition to clean water access and sustainable energy. This article presents a comprehensive assessment of the effects of COVID‐19 on these two sustainable development goals. Further, an integrated aspect of water and energy access for sustainable development is evaluated with insights on the effects of COVID‐19 on the water‐energy nexus. Additionally, technological evolution for building better water and energy supply systems is presented. An insight into developing robust healthcare systems and how the water and energy SDGs affect population dynamics is also speculated, which indicates varied short‐term adaption experiences, and highlights the need for a re‐evaluation of the water‐energy nexus. The integrated solutions contributing to stability of the water supply chain, energy storage, and policy making during and after an outbreak are critical to achieving developmental goals.
