An in-depth understanding {of the|from the|in the|on the|with the|of your} physicochemical properties of nanorods {during|throughout|in the course of|for the duration of|through} the initial {growth|development} {process|procedure|method|approach|course of action} {has a|features a|includes a} profound {impact|influence|effect} {on the|around the} rational {design|style|design and style} of high-performance nanorods catalysts. Herein, we {conducted|performed|carried out} a systematic DFT study {on the|around the} transition metal Co, Ni and alloyed nanoclusters/rods systems to simulate an atomic {process|procedure|method|approach|course of action} {from the|in the} initial nanoclusters {growth|development} to nanorods/wires. We {found|discovered|identified|located} that the {highly|extremely|very|hugely} active {sites|websites|web sites|internet sites|web-sites|web pages} of nanorods {depend on|rely on} an {interesting|fascinating|intriguing|exciting} electrostatic phenomenon. The surface electrostatic {potential|possible|prospective} {analysis|evaluation} shows that all nanoclusters and nanorods structures have formed σ-hole. {Unlike|In contrast to|As opposed to} nanoclusters, the σ-hole only {appears|seems} at terminal {sites|websites|web sites|internet sites|web-sites|web pages} in nanorods, {called|known as|referred to as|named} terminal σ-hole. The elemental composition in nanorods {has a|features a|includes a} {certain|particular|specific} influence {on the|around the} maximal surface electrostatic {potential|possible|prospective} (VS,max) i.e., terminal σ-hole. Interestingly, we {found|discovered|identified|located} that the terminal σ-hole formed in nanorods is {generally|usually|typically|normally|commonly|frequently} {higher|greater|larger} in magnitude than {smaller|smaller sized} nanoclusters. First-principle calculations show that terminal σ-hole is closely {related|associated|connected} {to the|towards the|for the} physicochemical activities of nanorods. {For example|For instance|As an example|By way of example|One example is}, the {work|function|perform|operate} function {of the|from the|in the|on the|with the|of your} directions forming terminal σ-hole is {smaller|smaller sized} than other directions. {More|Much more|A lot more|Far more|Additional|Extra} interestingly, we {found|discovered|identified|located} that in {almost|nearly|virtually|practically|just about|pretty much} all nanorods, compared with other atoms, the d-orbital {of the|from the|in the|on the|with the|of your} atoms forming terminal σ‑hole shifts close {to the|towards the|for the} Fermi level and exhibits a shallower d-band center, {showing|displaying} {higher|greater|larger} chemical activity. In {short|brief|quick}, {it is|it’s|it really is|it truly is|it can be|it is actually} {the first|the very first|the initial} time that we {discovered|found} terminal σ-hole in nanorods, explained the theoretical basis of terminal σ-hole in nanorod systems, and {provided|supplied|offered} theoretical guidance for the rational {design|style|design and style} of high-performance nanorods catalysts.
