于上文[9]類似，年億用作者首先合成了聯(lián)吡啶的COFs，年億用通過將Ni催化活性中心載入聯(lián)吡啶功能化的COFs中，在含水體系和可見光照射條件下，實(shí)現(xiàn)了光催化選擇性還原CO2制CO性能的大大增強(qiáng)。為了進(jìn)一步探索光催化的機(jī)理，個(gè)國(guó)國(guó)月作者使用自由基淬滅劑TEMPO進(jìn)行了可控光催化反應(yīng)，個(gè)國(guó)國(guó)月當(dāng)使用4當(dāng)量的TEMPO時(shí)，順式產(chǎn)物的產(chǎn)率顯著降低到3%，證實(shí)自由基的存在以及對(duì)于光催化反應(yīng)的重要性。

雖然與使用Pt做共催化劑的記錄有點(diǎn)差距，戶美該工作拓寬了COFs產(chǎn)氫的材料選擇，經(jīng)過優(yōu)化，有望將數(shù)值提高到可實(shí)際使用的范圍。

一：逼近COF簡(jiǎn)介COFs（CovalentOrganicFrameworks，逼近COFs）是一類新型的基于共價(jià)鍵連接的晶態(tài)有機(jī)多孔聚合物，它是利用共價(jià)化學(xué)反應(yīng)在分子尺度上將結(jié)構(gòu)單元進(jìn)行有序排列，進(jìn)而形成有序的框架結(jié)構(gòu)?？癖糂acklightMasterDrive的幾個(gè)重要參數(shù)：第一：最大亮度。

第四點(diǎn)大量的LED燈還會(huì)帶來(lái)一個(gè)能源消耗的問題，年億用但索尼擁有先進(jìn)的驅(qū)動(dòng)算法，年億用可以非常好的平衡能源消耗，以索尼85寸的原型機(jī)來(lái)說(shuō)，能在超高亮度的情況下保持和普通85寸電視基本一致的功耗水平。個(gè)國(guó)國(guó)月BacklightMasterDrive最大亮度可以達(dá)到4000尼特或者cd/m2。

戶美這個(gè)立體色彩空間就意味著這個(gè)視頻格式能帶來(lái)多大的色彩數(shù)量。BacklightMasterDrive，逼近讓超高亮度成為可能HDR的標(biāo)準(zhǔn)有了，逼近可是能夠更好的支持它的硬件在哪呢?當(dāng)然現(xiàn)在也有局部光控技術(shù)的LCD，讓普通的LCD對(duì)于暗部場(chǎng)景做到很好的亮度等級(jí)控制，從而既能保持原有的色彩，同時(shí)又有優(yōu)秀的白平衡。
