MAX phase metal carbide-enabled triboelectric nanogenerator for integrated ammonia generation

Electrochemical ammonia synthesis at ambient conditions offers a promising and eco-friendly alternative to conventional methods, which are highly energy-intensive and major contributors to global greenhouse gas emissions. To make this approach sustainable, it must be integrated with a renewable, clean, and affordable energy source. Here, we developed an eco-friendly approach to produce electrocatalytic ammonia powered …

Magnetically Propelled Microrobots toward Photosynthesis of Green Ammonia from Nitrates

Ammonia (NH₃) production is a critical industrial process, as ammonia is a key component in fertilizers, essential for global agriculture and food production. However, the current method of synthesizing ammonia, the Haber-Bosch process, is highly energy-intensive, and relies on fossil fuels, contributing substantially to greenhouse gas emissions. Moreover, the centralized nature of the Haber-Bosch process …

Ultrathin manganese oxides enhance the electrocatalytic properties of 3D printed carbon catalysts for electrochemical nitrate reduction to ammonia

Electrochemical nitrate reduction reaction (NO3RR) is a promising approach to remedying the environmental pollution from nitrate, and simultaneously a sustainable alternative to traditional Haber-Bosch process especially for decentralized ammonia production. Here, we firstly explore the electrocatalytic activity of two 3D printed carbon frameworks consisting of 0-dimentional (0D) carbon black and 1-dimentional (1D) carbon nanotubes towards …
