ʻO Tungsten Sulfide (WS2): Hana a me ka hoʻohana ʻana

WS2, i ʻike ʻia hoʻi ʻo tungsten sulfide he hina hina, ʻōnaehana hexagonal, semiconductor a me diamagnetic. Loaʻa iā ia ke koina friction haʻahaʻa loa (0.03), ke kū'ē kiʻekiʻe loa o ke kaomi a me ke kū'ē oxidation (hoʻomaka ka decomposition ma 450 ℃ i ka lewa, He kūpono ia no ke kiʻekiʻe o ka mahana, ke kaomi kiʻekiʻe, ka vacuum kiʻekiʻe, ka ukana kiʻekiʻe, ka wikiwiki kiʻekiʻe, ka radiation kiʻekiʻe, ka corrosion ikaika, ka mahana haʻahaʻa loa a me nā kūlana ʻino ʻē aʻe.

WS2 / tungsten sulfides / tungsten disulfides / tungsten(IV)He hui ka sulfide i loaʻa ka nānā ʻana i loko o ke kaiāulu ʻepekema ma muli o kona mau waiwai kūikawā a me nā noi hiki. Ma kēia ʻatikala, e ʻimi mākou i ke ʻano o WS2, kona mau waiwai, a me kona mau hoʻohana hiki i nā ʻano like ʻole.

WS2he hui i hana ʻia me nā ʻātoma tungsten a me ka sulfur, me ke ʻano kemika o W(S2). No ka ʻohana o nā dichalcogenides metala hoʻololi (TMDs), ʻo ia hoʻi nā mea papa me kahi ʻano like me graphene. Loaʻa iā WS2 kahi ʻano papa i hana ʻia me nā ʻātoma tungsten i hoʻopaʻa ʻia ma waena o nā papa o nā ʻātoma sulfur. Hoʻohana ʻo WS2 i kahi ʻano papa e pili ana iMoS2(Molybdenum Disulfide), me nā ʻātoma W i waiho ʻia ma ka poepoe hoʻohui prismatic trigonal, hāʻawi kēia ʻano papa iā WS2 i kona mau waiwai kū hoʻokahi a hoʻolilo iā ia i mea hoihoi no ka noiʻi ʻepekema a me nā noi ʻenehana.

ʻO kekahi o nā waiwai i ʻike nui ʻia oWS2ʻo ia kona mau waiwai lubricating. He haʻahaʻa ka coefficient o ka friction o WS2, ka mea e lilo ai ia i lubricant maikaʻi loa no nā noi like ʻole. Ua hoʻohana ʻia ia ma ke ʻano he lubricant paʻa i nā wahi wela kiʻekiʻe a me ke kaomi kiʻekiʻe, e like me nā ʻoihana aerospace a me nā kaʻa. ʻO ke ʻano papa o WS2 e hiki ai iā ia ke paheʻe maʻalahi ma luna o kekahi, e hōʻemi ana i ka friction a me ka ʻaʻahu ma waena o nā ʻili.

Ma waho aʻe o kona mau waiwai lubricating,WS2hōʻike pū i ke ʻano semiconducting. ʻO ia hoʻi, hiki ke hoʻohana ʻia i nā mea uila a me nā noi optoelectronic. Ua hōʻike ʻo WS2 i ka hiki ke hoʻohana ʻia i nā transistors, photodetectors, a me nā cell solar ma muli o kona mau waiwai uila kū hoʻokahi. ʻO kona hiki ke omo pono a hoʻopuka i ka mālamalama e lilo ia i mea hoʻohiki no nā mea optoelectronic hanauna e hiki mai ana.

Eia kekahi,WS2Ua aʻo ʻia no kona hiki ke hoʻohana ʻia i nā noi catalysis a me ka mālama ʻana i ka ikehu. ʻO kona ʻili kiʻekiʻe a me ka hana catalytic e lilo ia i moho hoʻohiki no ka hoʻohana ʻana i nā cell wahie, nā hopena hoʻomohala hydrogen, a me nā kaʻina hana catalytic ʻē aʻe. Ua noiʻi ʻia hoʻi nā mea i hoʻokumu ʻia ma WS2 no ko lākou hiki ke hoʻohana ʻia i nā mea mālama ikehu, e like me nā pila a me nā supercapacitors, ma muli o ko lākou conductivity kiʻekiʻe a me nā waiwai electrochemical.

Nā waiwai kūikawā oWS2ua huki pū ʻia ka hoihoi i ke kahua o ka nanotechnology. Ua synthesized a ua aʻo ʻia nā nanoparticles a me nā nanosheets WS2 no ko lākou hiki i nā noi nanotechnology like ʻole, e like me nanoelectronics, nanophotonics, a me nanomedicine. ʻO ka hiki ke hoʻoponopono a kāohi i nā waiwai o WS2 ma ka nanoscale e wehe i nā mea hou no ka hoʻomohala ʻana i nā nanomaterials holomua a me nā nanodevices.

I ka hōʻuluʻulu manaʻo,WS2 (tungsten sulfides)nā hoʻohana aʻe:

1. Hoʻohana nui ʻia ʻo WS2 no nā mea hoʻoulu aila;

2. He mea hoʻouluulu ikaika hou ʻo WS2;

3. Hiki ke hoʻohana ʻia ʻo WS2 ma ke ʻano he mau lubricants paʻa, nā lubricants ʻili maloʻo, nā mea hui hoʻohui ponoʻī;

4. ʻO WS2 ka hana ʻana i nā mea hoʻohui lubricant hana kiʻekiʻe;

5. Hiki ke hoʻohana ʻia ʻo WS2 ma ke ʻano he mau wahie o ka anode, ka anode pila electrolyte organik, ka oxidation o ka sulfur dioxide i loko o ka waikawa ikaika i loko o ka anode a me ka sensor anode;

6. Hoʻohana ʻia ʻo WS2 e hana i nā composites nano-ceramic;

7. He mea semiconductor maikaʻi ʻo WS2.

I ka hopena,WS2, a i ʻole tungsten sulfide, he hui me nā ʻano waiwai kū hoʻokahi a me nā noi hiki. ʻO kona mau waiwai lubricating, ke ʻano semiconducting, ka hana catalytic, a me ka hiki i ka nanotechnology e hoʻolilo iā ia i mea hana maʻalahi me nā manaʻolana hoʻohiki ma nā ʻano like ʻole. Ke hoʻomau nei ka noiʻi ʻana i ka WS2 i ka holomua, he mea hiki ke ʻike mākou i nā hoʻomohala hou aʻe a me nā noi o kēia hui hoihoi i ka wā e hiki mai ana.
