| 中文摘要 | 由於磺基水楊酸（SSA）是一種廣泛使用的醫學中間體，SSA釋放到水中會對水生環境造成嚴重破壞。由於其生物降解性低，因此需要化學氧化工藝來消除SSA。由於越來越多地開發基於硫酸根基（SR）的化學氧化工藝以降解新興污染物，因此建立有效的基於SR的SSA降解工藝非常重要。由於過一硫酸鹽（PMS）是被廣泛採用的SR來源，並且鈷（Co）被證實是激活PMS的有用金屬，因此在此提出了一種簡便的技術來開發由Co3O4組成的具有二維片狀和多孔結構的多相催化劑。用於增強PMS活化以降解SSA的催化活性。具體而言，採用由Co和具有六方奈米片結構的三聚硫氫酸（TMT）組成的Co基配位聚合物作為前體。煅燒後，CoTMT轉化為多孔Co3O4奈米片（PCNS），並且該PCNS與商業Co3O4 NP表現出明顯的表面反應性和質地結構特性。這些有利的特徵使PCNS能夠顯示出比Co3O4 NP高得多的催化活性，以激活PMS降解SSA。 PCNS還可以重複使用多個週期，以激活PMS降解SSA，而不會損失催化活性。 |
| 英文摘要 | As sulfosalicylic acid (SSA) is a widely-employed medical intermediate, the release of SSA into water causes serious damage to the aquatic environment. Because of its low bio-degradability, chemical oxidation processes are necessitated to eliminate SSA. Since sulfate-radical (SR)-based chemical oxidation processes are increasingly developed for degradation of emerging contaminants, it is important to establish effective SR-based processes for SSA degradation. As Peroxymonosulfate (PMS) is an extensively adopted source for SR and cobalt (Co) is validated as a useful metal to activate PMS, a facile technique is proposed here to develop a heterogeneous catalyst comprised of Co3O4 with a 2D sheet-like and porous configuration for enhancing catalytic activity for PMS activation to degrade SSA. Specifically, a Co-based coordination polymer consisting of Co and trismercaptotriazine (TMT) with a hexagonal nanosheet structure is adopted as a precursor. After calcination, CoTMT is transformed to porous Co3O4 nanosheet (PCNS), and this PCNS exhibits distinct surficial reactivity and textural properties from the commercial Co3O4 NP. These advantageous features enable PCNS to show much higher catalytic activities than the Co3O4 NP for activation of PMS to degrade SSA. PCNS is also reusable for multiple cycles for activating PMS to degrade SSA without loss of catalytic activity. |
