Plasmon‐Driven Nitrogen Photoreduction to Ammonia Using Silica‐Encapsulated Au Nanostar/TiO2 Nanohybrids

open access: yesAdvanced Energy Materials, EarlyView.
Photocatalytic N₂ reduction is a sustainable method for ammonia production. Au nanostars (AuNST) with TiO2 excel, especially when encased in mesoporous silica, enhancing stability and selectivity without scavengers. Electromagnetic fields at nanostar spikes drive hot‐electron transfer to TiO2 for N2 reduction under visible light, while hot holes ...

Peroxide‐Driven Nitrogen Fixation Reactions for Energy Storage Applications

open access: yesAdvanced Energy Materials, EarlyView.
Sustainable ammonia synthesis from air as a hydrogen energy carrier and storage medium is demonstrated via an efficient dual‐step electrochemical approach at ultralow overpotential (−0.1 V vs. RHE). Atmospheric nitrogen is first oxidized to nitrate using in situ generated peroxide, then directly converts to ammonia on the same electrode, achieving ...

A Scoping Review of Nudges for Enhancing Agricultural Policy

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT Following PRISMA guidelines, we conduct a scoping review on 18 empirical studies on nudging interventions for farmers in Europe and the USA. The evidence on the effectiveness of nudges is mixed. Some studies demonstrate positive outcomes, particularly when nudges are combined with other interventions; others report no effect or negative ...
