Pathways to Carbon Neutrality: The Role of Environmental Governance, Environmental Technology, Renewable Energy Transition, and Economic Policy Uncertainty in Africa

Business Strategy and the Environment, EarlyView.
ABSTRACT As climate change and environmental deterioration continue to escalate due to substantial CO2 emissions, nations worldwide are implementing approaches to alleviate CO2 emissions and accomplish carbon neutrality (CNE) goals. The current study examined CNE objectives for five selected nations in Africa, spanning from 1990 to 2022.

Energy‐Efficient Induction Carbonization: Tailoring Pore Structures in Hard Carbon Anodes Toward Enhanced Electrochemical Performance

Carbon Energy, EarlyView.
ABSTRACT Hard carbon (HC) is currently the predominant anode material for sodium‐ion batteries; however, its practical application is still limited by insufficient initial Coulombic efficiency (ICE) and plateau capacity. Meanwhile, conventional HC production relies on energy‐intensive carbonization processes with considerable carbon emissions. Here, an

Boosting Sodium Storage Activity and Kinetics of Hard Carbon by Remodeling Oxygen Chemistry

Carbon Energy, EarlyView.
A surface oxygen remodeling strategy is proposed to finely furnish the pseudographitic structure of hard carbon with rich closed pores and expanded interlayer spacings. Accordingly, the sodiation reactivity and kinetics are greatly reinforced to afford an elevated capacity of 360 mAh g−1 and outstanding rate capability of 225 mAh g−1 at 2 A g−1 ...
