Nyocha na Ndụmọdụ maka Mkpuchi Batrị nkewa

Onye ahịa na-emepụta ihe ndị na-ekewa batrị, a pụkwara iji obere ihe na-ejikọta ihe kpuchie elu ihe nkewa ahụ, nke a na-ejikarị alumina (Al₂O₃) mee ihe. Ha na-achọzi ihe ndị ọzọ na-egbochi ọkụ iji dochie alumina, yana ihe ndị a chọrọ:

• Ibelata ire ọkụ dị irè na 140°C(dịka ọmụmaatụ, ire ere iji wepụta gas ndị na-adịghị arụ ọrụ).
• Nkwụsi ike nke elektrọkemịkalụna ndakọrịta na ihe ndị dị na batrị.

Ihe ndị na-egbochi ire ọkụ na nyocha akwadoro

1. Ihe ndị na-egbochi ire ọkụ nke phosphorus-nitrogen (dịka ọmụmaatụ, Ammonium Polyphosphate nke agbanwere agbanwe (APP) + Melamine)

Usoro:

• Isi iyi asịd (APP) na isi iyi gas (melamine) na-arụkọ ọrụ iji wepụta NH₃ na N₂, na-agwakọta oxygen ma na-emepụta oyi akwa cha iji gbochie ọkụ.
  Uru:
• Njikọta phosphorus-nitrogen nwere ike ibelata okpomọkụ nke ire ere (enwere ike ịgbanwe ya ruo ~140°C site na nhazi nano ma ọ bụ nhazi).
• N₂ bụ gas na-adịghị arụ ọrụ; NH₃ mmetụta na electrolyte (LiPF₆) chọrọ nyocha.
  Ihe Ndị A Ga-atụle:
• Nyochaa nkwụsi ike nke APP na electrolytes (zere hydrolysis ka ọ ghọọ phosphoric acid na NH₃). Mkpuchi silica nwere ike ime ka nkwụsi ike ka mma.
• A chọrọ nnwale ndakọrịta elektrọnik (dịka ọmụmaatụ, voltammetry cyclic).

2. Ihe ndị na-egbochi ọkụ nke dabere na nitrogen (dịka ọmụmaatụ, Sistemụ Azo Compound)

Onye anamachọihe:Azodicarbonamide (ADCA) yana ihe ndị na-eme ka ihe rụọ ọrụ (dịka ọmụmaatụ, ZnO).
Usoro:

• Okpomọkụ ire ere nke a na-agbanwe agbanwe ruo 140–150°C, na-ewepụta N₂ na CO₂.
  Uru:
• N₂ bụ ezigbo gas na-adịghị arụ ọrụ nke ọma, nke na-adịghị emerụ batrị ahụ.
  Ihe Ndị A Ga-atụle:
• Ihe ndị na-achịkwa ngwaahịa (dịka ọmụmaatụ, CO, NH₃).
• Microencapsulation nwere ike ịgbanwe ọnọdụ okpomọkụ nke mmebi ahụ kpọmkwem.

3. Sistemụ Mmeghachi Omume Okpomọkụ Carbonate/Acid (dịka ọmụmaatụ, Microcapsulated NaHCO₃ + Acid Source)

Usoro:

• Mkpụrụ obere kapsụl na-agbawa na 140°C, na-akpali mmeghachi omume n'etiti NaHCO₃ na organic acid (dịka ọmụmaatụ, citric acid) iji wepụta CO₂.
  Uru:
• CO₂ anaghị arụ ọrụ nke ọma ma dịkwa nchebe; a na-achịkwa okpomọkụ mmeghachi omume.
  Ihe Ndị A Ga-atụle:
• Iọn sodium nwere ike igbochi njem Li⁺; tụlee nnu lithium (dịka ọmụmaatụ, LiHCO₃) ma ọ bụ ime ka Na⁺ ghara ịrụ ọrụ na mkpuchi ahụ.
• Mee ka mkpuchi dịkwuo mma maka ọnọdụ okpomọkụ ụlọ.

Nhọrọ Ndị Ọzọ Nwere Ike Ime

• Usoro ihe eji arụ ọrụ nke metal-organic (MOFs):dịka ọmụmaatụ, ZIF-8 na-agbaze n'okpomọkụ dị elu iji wepụta gas; enyocha maka MOFs nwere okpomọkụ mmebi kwekọrọ.
• Zirkonium Phosphate (ZrP):Ọ na-emepụta ihe mgbochi mgbe okpomọkụ gbawara, mana ọ nwere ike ịchọ nha nano iji belata okpomọkụ gbawara.

Ndụmọdụ Nnwale

1. Nyocha Thermogravimetric (TGA):Chọpụta okpomọkụ nke ire ere na njirimara mwepụta gas.
2. Nnwale Elektrọnik:Nyochaa mmetụta dị na ionic conductivity, interfacial impedance, na arụmọrụ ịgba ígwè.
3. Nnwale Nkwụsị Ọkụ:dịka ọmụmaatụ, ule ọkụ kwụ ọtọ, nha mbelata okpomọkụ (na 140°C).

Mmechi

Iheihe na-egbochi ire ọkụ nke phosphorus-nitrogen emezigharịrị (dịka ọmụmaatụ, APP a kpụchara akpụcha + melamine)A na-atụ aro ka e buru ụzọ mee ya n'ihi na ọ naghị ebelata ire ọkụ nke ọma, ọ na-emekwa ka okpomọkụ ya ghara ịdịkwa mma. Ọ bụrụ na a ga-ezere NH₃,sistemụ ngwakọta azoma ọ bụsistemụ mwepụta CO₂ nke e ji obere mkpụrụ osisi kpuchiebụ nhọrọ ndị dị irè. A na-adụ ọdụ ka e jiri usoro nnwale mee ihe iji hụ na e nwere ike ịkwụsi ike na usoro electrochemical.
