Mphamvu zowonjezera zam'tsogolo: Madzi a m'nyanja

Palibe kukaikira za izo, kutentha kwa dziko ndi zenizeni, ndi vuto kukula. Ngakhale kuti ena akusankha kunyalanyaza zizindikiro ndi zomwe apatsidwa, ena akuyang'ana kuti apite ku mphamvu zowonjezera komanso zoyera. Ofufuza angapo a ku yunivesite ya Osaka atero apezeka njira yopangira mphamvu zowonjezera zomwe zimagwiritsa ntchito chimodzi mwazinthu zazikulu kwambiri padziko lapansi, madzi a m'nyanja.

VUTOLO:

Mphamvu ya dzuwa ndi gwero lalikulu la mphamvu zowonjezera. Komabe, kodi mphamvu ya dzuwa tingaigwiritse ntchito bwanji pamene dzuŵa likubisala? Yankho limodzi ndikusintha mphamvu ya dzuwa kukhala mphamvu yamankhwala yomwe ingagwiritsidwe ntchito ngati mafuta. Pochita kutembenukaku, kumatha kusungidwa ndikusuntha. Hydrogen (H2) ndi amene angathe kutembenuka. Itha kupangidwa pogawa mamolekyu amadzi (H2O) pogwiritsa ntchito njira yotchedwa "photocatalysis". Photocatalysis ndi pamene kuwala kwa dzuwa kumapereka mphamvu ku chinthu china chomwe chimakhala ngati "chothandizira". Chothandizira chimafulumizitsa kuchuluka kwa zomwe zimachitika. Photocatalysis imapezeka pozungulira ife, kuwala kwa dzuwa kumagunda chlorophyll ya zomera (chothandizira) m'maselo awo a zomera, zomwe zimawalola kutulutsa mpweya, ndi shuga yomwe ili gwero la mphamvu!

Komabe, monga ofufuza anati m'mapepala awo, "kuchepa kwa mphamvu ya dzuwa kutembenuza mphamvu ya H2 kupanga ndi vuto la kusunga mpweya wa H2 walepheretsa kugwiritsa ntchito H2 ngati mafuta a dzuwa."

CHOLINGA:

Lowetsani hydrogen peroxide (H2O2). Monga American Energy Independence zolemba, “Hydrogen peroxide, ikagwiritsidwa ntchito popanga mphamvu, imapanga madzi oyera okha ndi okosijeni monga chotulukapo, motero imatengedwa ngati mphamvu yoyera ngati haidrojeni. Komabe, mosiyana ndi hydrogen, H2O2 [hydrogen peroxide] imakhala yamadzimadzi m’malo otentha, choncho imatha kusungidwa ndi kunyamulidwa mosavuta.” Vuto linali loti njira yapitayi yopangira hydrogen peroxide idagwiritsa ntchito photocatalysis pamadzi oyera. Madzi oyera ndi oyera monga momwe amakhalira. Ndi kuchuluka kwa madzi oyera omwe amagwiritsidwa ntchito pokonzekera, zikutanthauza kuti si njira yotheka yopangira mphamvu zokhazikika.

Apa ndi pamene madzi a m'nyanja amabwera. Poganizira kuti madzi a m'nyanja amapangidwa ndi chiyani, ofufuzawo adawagwiritsa ntchito mu photocatalysis. Chotsatira chake chinali kuchuluka kwa hydrogen peroxide yomwe inali yokwera kwambiri kuti igwiritse ntchito selo yamafuta ya hydrogen peroxide (selo yamafuta ili ngati batire, imafunikira mafuta osalekeza kuti ayende.)

Njira yopangira hydrogen peroxide yamafuta ndi ntchito yophukira yokhala ndi malo oti ikule. Palinso funso la kutsika mtengo, ndikuligwiritsa ntchito pamlingo waukulu, osati ngati mafuta. Mmodzi mwa ofufuza omwe adakhudzidwa, Shunichi Fukuzumi, adadziwika mu nkhani kunena kuti, "M'tsogolomu, tikukonzekera kupanga njira yopangira njira zotsika mtengo, zopangira zazikulu za H2O2 kuchokera kumadzi a m'nyanja," Fukuzumi posits, "Izi zikhoza kulowa m'malo mwa H2O2 yotsika mtengo ya H2 kuchokera ku H2 (makamaka. kuchokera ku gasi) ndi OXNUMX."
