Progress, Challenges, and Policy Insights for Collaborative Innovation Pilots on Pollution and Carbon Emission Reduction

This paper systematically reviews the progress and achievements of China's collaborative innovation pilots for pollution and carbon emission reduction, identifies existing problems, and proposes targeted recommendations. As of the first batch, 64 pilot units (21 cities and 43 industrial parks) have issued implementation plans, with overall smooth progress and notable phased outcomes. Most pilots have actively promoted institutional and mechanism innovations, achieving substantial advancements in key sectors and critical areas, and yielding replicable practices. However, challenges persist, including fragmented interdepartmental collaboration, insufficient alignment of management systems, funding shortages for synergistic projects, and inadequate technological support. Recommendations include intensifying awareness campaigns, establishing coordinated promotion mechanisms, accelerating management system implementation, advancing core technology R&D, conducting progress evaluations, and amplifying publicity. For the second batch, suggestions focus on expansion strategies, pilot types, and selection methods, emphasizing incremental tasks, diverse pilot subjects (from provincial to enterprise levels), and clear articulation of expected outcomes and demonstration targets. The paper underscores the need to transform local experiences into institutionalized frameworks, fostering a four-dimensional synergy of carbon reduction, pollution control, green expansion, and economic growth, thereby contributing to China's ecological civilization and global climate governance.

Redox-Mediated Stabilization of Ultrasmall Au25 Nanoclusters in Amine-Functionalized MOF for Robust Photocatalytic Antibacterial Applications

Noble metal nanoclusters (MNCs) possess atomically precise structures and tunable compositions, yet their practical deployment is constrained by rapid oxidation-induced structural degradation and ligand detachment, leading to aggregation during storage and catalysis. This study introduces a redox-mediated stabilization strategy by integrating ultrasmall Au25 nanoclusters with amine-functionalized UiO-66-NH2. The uniformly dispersed amine groups act as reductive reagents, suppressing Au oxidation while reinforcing thiol-terminated ligand anchoring via dynamic coordination. This dual stabilization preserves the initial ultrasmall size and structural integrity of Au25 NCs under ambient storage and light irradiation. The engineered type-II heterojunction between Au25 NCs and UiO-66-NH2 enhances visible-light harvesting and charge separation, enabling efficient O2 activation to reactive oxygen species (ROS). The Au25/UiO-66-NH2 composites achieve 99.999% bacterial inactivation against Escherichia coli within 40 min under visible light, retaining high efficacy after five reuse cycles. Integration into wearable fabrics demonstrates potential for continuous antibacterial protection. This work establishes amine-functionalized MOFs as universal redox-active supports for stabilizing metastable MNCs, offering a versatile platform for durable photocatalytic systems in environmental and biomedical applications.
