Research progress of palladium-based catalysts for oxidation of low concentration methane

能源环境保护, 2023
Methane (CH_4) is an important greenhouse gas that is 25 times that its CO_2 equivalent. There is low concentration (0.05% ~0.5%) CH_4 leakage in marine natural gas engine exhaust.

From Green Governance to Biodiversity Strategy: The Role of Environmentally Experienced Directors in Chinese Firms

Business Strategy and the Environment, EarlyView.
ABSTRACT This study investigates how directors with environmental protection (EP) backgrounds influence corporate biodiversity concern (BIO) among Chinese A‐share listed firms from 2008 to 2023. Drawing on Upper Echelons Theory, we argue that directors' environmental expertise shapes firms' biodiversity strategies.
