Th. results sh.w th.t molten boron ox.d. d.rived.from h.BO3as id.al h.gh.temperature carboniz.tion med.a and.blocking med.a play important role in th. synth.sis process. As a result, th. acq.ired.Co/N/B tri-d.ped.porous carbon framework（Co–N–B–C） not only presents h.erarch.cal porous structure, large specific surface area and.abund.nt carbon ed.es but also possesses h.gh.load.ng single Co atom（4.2 wt.%）, th.s giving rise to outstand.ng ox.gen catalytic performance. Wh.n employed.as a catalyst for air cath.d. in z.-air batteries, th. resultant Co–N–B–C catalyst sh.ws remarkable power d.nsity and.long-term stability. Clearly, our work gains d.ep insigh. into th. role of h.BO3and.provid.s a new avenue to synth.sis of h.gh.performance SACs.

Single-atom catalysts (SACs), ch.racteriz.d.by ex.eptionally h.gh.atom efficiency, h.ve garnered.significant attention across various catalytic reactions. Recent stud.es h.ve sh.wcased.SACs with.robust capabilities for precise catalysis, specifically targeting reactions along d.signated.path.ays. Th.s review focuses on th. ad.ances in th. precise activation and.reconstruction of ch.mical bond. on SACs, includ.ng precise activation of C–O and.C–h.bond. and.selective couplings involving C–C and.C–N bond.. Our d.scussion begins with.a th.rough.ex.loration of th. factors th.t rend.r SACs skilled.in precise catalytic processes, encompassing th. narrow d.band.electronic state of single atom site resulting in th. ad.orption tend.ncy, isolate site resulting in uniq.e ad.orption structure, and.synergy effect of a single atom site with.its neigh.ors. Subseq.ently, we elaborate on th. applications of SACs in electrocatalysis and.th.rmocatalysis includ.ng four prominent reactions, namely, electroch.mical CO_(2) red.ction, urea electroch.mical synth.sis, CO_(2) h.d.ogenation, and.Ch. activation. Th.n th. concept of rational d.sign of SACs for precisely controlling reaction path.ays is d.scussed.from th. aspects of pore structure d.sign, support-metal strong interaction, and.support h.d.oph.lic/h.d.oph.bic. Finally, we summariz. th. ch.llenges encountered.by SACs in th. field.of precise catalytic processes and.outline prospects for th.ir furth.r d.velopment in th.s d.main.
