Soil is the largest carbon(c) reservoir in terrestrial ecosystems and plays a crucial role in regulating the global c cycle and climate *** nitrogen(N) deposition has been widely considered as a critical factor affecting soil organic carbon(SOc) storage, but its effect on SOc components with different stability remains unclear. Here, we analyzed extensive empirical data from 304 sites worldwide to investigate how SOc and its components respond to N addition. Our analysis showed that N addition led to a significant increase in bulk SOc(6.7%), with greater increases in croplands(10.6%) and forests(6.0%) compared to grasslands(2.1%). Regarding SOc components, N addition promoted the accumulation of plant-derived c(9.7%–28.5%) over microbial-derived c(0.2%), as well as labile(5.7%) over recalcitrant components(–1.2%), resulting in a shift towards increased accumulation of plant-derived labile c. consistently, N addition led to a greater increase in particulate organic c(11.9%) than mineral-associated organic c(3.6%), suggesting that N addition promotes c accumulation across all pools, with more increase in unstable than stable pools. The responses of SOc and its components were best predicted by the N addition rate and net primary productivity. Overall, our findings suggest that N enrichment could promote the accumulation of plant-derived and non-mineral associated c and a subsequent decrease in the overall stability of soil c pool, which underscores the importance of considering the effects of N enrichment on SOc components for a better understanding of c dynamics in soils.

Zeolite nanosheets with a short b-axis thickness are highly desirable in lots of catalytic reactions due to their reduced diffusion resistance. Nevertheless, conventional synthesis methods usually require expensive structure-directing agents(SDAs), pricey raw materials, and eco-unfriendly fluorine-containing additives. Here, we contributed a cost-effective and fluoride-free synthesis method for synthesizing high-quality MFI zeolite nanosheets through a Silicalite-1(Sil-1) seed suspension and urea cooperative strategy, only with inexpensive colloidal silica as the Si source. Our approach was effective for synthesizing both Sil-1 and aluminum-containing ZSM-5 nanosheets. By optimizing key synthesis parameters,including seed aging time, seed quantity, and urea concentration, we achieved precise control over the crystal face aspect ratio and b-axis thickness. We also revealed a non-classical oriented nanosheet growth mechanism, where Sil-1 seeds induced the formation of quasi-ordered precursor particles, and the(010)crystal planes of these particles facilitated urea adsorption, thereby promoting c-axis-oriented *** obtained ZSM-5 nanosheets exhibited exceptional catalytic performance in the benzene alkylation with ethanol, maintaining stability for over 500 h, which is 5 times longer than traditional ZSM-5 catalysts. Furthermore, large-scale production of ZSM-5 nanosheets was successfully carried out in a 3 L highpressure autoclave, yielding samples consistent with those from laboratory-scale synthesis. This work marks a significant step forward in the sustainable and efficient production of MFI nanosheets using inexpensive and environmentally friendly raw materials, offering the broad applicability in catalysis.
