The roots of organic agriculture [PDF]

, 2012
It was concern about the replacement of traditional organic fertilizers by the then new chemical fertilizers that precipitated the early stirrings of disquiet about the prevailing direction of agriculture and which has grown into today’s organic ...

Low temperature plasma-catalytic NOx synthesis in a packed DBD reactor: effect of support materials and supported active metal oxides [PDF]

, 2016
The direct synthesis of NOx from N2 and O2 by non-thermal plasma at an atmospheric pressure and low temperature is presented, which is considered to be an attractive option for replacement of the Haber-Bosch process.

Ruthenium‐Based Catalysts Supported on Lanthanum and Carbon‐Modified Alumina for Low‐Pressure Ammonia Synthesis

Carbon and Hydrogen, EarlyView.
We proposed a new “hydrogen transfer–desorption” synergistic regulation strategy and developed a Ru/Al2O3‐La‐C catalyst with dual functions. La‐O sites were constructed and carbon components were introduced into the catalyst to regulate the two key steps of hydrogen transfer and desorption on the catalyst surface, respectively, solving the problem of ...

An Ambient Photocatalytic Approach to In‐Situ Prepare Cobalt/Cobalt Phosphide and Cobalt/Cobalt Phosphide@Graphene Heterojunction Nanomaterials With Optimized Charge Separation Effects for Highly Efficient Relayed Electrocatalytic NOX− Reduction to NH3

Carbon Energy, EarlyView.
A visible‐light‐driven ambient photocatalytic method in‐situ fabricates Co/CoP‐x and Co/CoP@rGO heterojunction with enhanced charge separation, enabling highly efficient relayed electrocatalytic NOx− reduction to NH3 with outstanding Faraday efficiency and ammonia productivity.

Recent Advances in Photocatalytic Urea Synthesis via C−N Coupling From C/N‐Containing Species: A Mini Review

EcoEnergy, EarlyView.
This review systematically compares photocatalytic urea synthesis from various C (CO2, CO, CH3OH) and N (N2, NH3, NO3−) sources. It highlights C–N coupling mechanisms, key challenges, and future directions, offering a framework to guide rational catalyst design for sustainable, solar‐driven urea production.
