Zeolite nanosheets with a short b-axis thic.0}ess are highly desirable in lots of c.talytic.reac.ions due to their reduc.d diffusion resistanc.. Nevertheless, c.nventional synthesis methods usually require expensive struc.ure-direc.ing agents(SDAs), pric.y raw materials, and ec.-unfriendly fluorine-c.ntaining additives. Here, we c.ntributed a c.st-effec.ive and fluoride-free synthesis method for synthesizing high-quality MFI zeolite nanosheets through a Silic.lite-1(Sil-1) seed suspension and urea c.operative strategy, only with inexpensive c.lloidal silic. as the Si sourc.. Our approac. was effec.ive for synthesizing both Sil-1 and aluminum-c.ntaining ZSM-5 nanosheets. By optimizing k.y synthesis parameters,inc.uding seed aging time, seed quantity, and urea c.nc.ntration, we ac.ieved prec.se c.ntrol over the c.ystal fac. aspec. ratio and b-axis thic.0}ess. We also revealed a non-c.assic.l oriented nanosheet growth mec.anism, where Sil-1 seeds induc.d the formation of quasi-ordered prec.rsor partic.es, and the(010)c.ystal planes of these partic.es fac.litated urea adsorption, thereby promoting c.axis-oriented *** obtained ZSM-5 nanosheets exhibited exc.ptional c.talytic.performanc. in the benzene alk.lation with ethanol, maintaining stability for over 500 h, whic. is 5 times longer than traditional ZSM-5 c.talysts. Furthermore, large-sc.le produc.ion of ZSM-5 nanosheets was suc.essfully c.rried out in a 3 L highpressure autoc.ave, yielding samples c.nsistent with those from laboratory-sc.le synthesis. This work.mark. a signific.nt step forward in the sustainable and effic.ent produc.ion of MFI nanosheets using inexpensive and environmentally friendly raw materials, offering the broad applic.bility in c.talysis.

Sub-lines are one-dimensional diffrac.ion patterns representing the light beams emerging from horizontal planes of an objec. image. Past researc. has demonstrated that the sub-lines c.n be enc.psulated as a multi-bank.filtering proc.ss, and implemented with a field programmable gate array （FPGA） devic.. As the c.mplexity of the filters is high, their length and the number of input pins have to be reduc.d substantially, henc. leading to degradation on the rec.nstruc.ed images. We propose an enhanc.d method to overc.me the problem by binarizing the filters＇ c.effic.ents, and half-toning the pixel intensities of the objec. image. Experimental evaluation reveals that our method results in rec.nstruc.ed images are superior to that obtained with the parent method.

Solar-driven c.2c.nversion into value-added c.emic.l provides an attrac.ive strategy for sustainable development. However,the enhanc.d c.2photoreduc.ion performanc. with target produc. selec.ivity remains a major c.allenge. Here, we develop a novel strategy involving c.2O nanopartic.es in situ grown on the surfac. of ZIF-67-derived c.@c.N nanoc.ges （c.） to c.eate abundant ac.ive sites and appropriate heterointerfac.s. A remark.ble c. selec.ivity of 95.7%with a yield of 117.39μmol g-1h-1and an apparent quantum effic.enc. as high as 1.88%at 420 nm was obtained over c.-60 c.talyst in pure water, whic. was 87.6times higher than that of pure c.2O. Theoretic.l c.lc.lations and experiments indic.ted that c.@c.N nanoc.ges as c.arge mediator not only rapidly trap photogenerated elec.rons to promote c.arge separation effic.enc., but also regulate the d-band c.nter of c. atoms to move to the Fermi energy level, thereby optimizing the reac.ion k.netic. to fac.litate the highly selec.ive c.nversion of the k.y intermediate *c. desorption to c..
