Choose the Co(NO3 )2 ×6H2 O(aq) as precursor and NaOH as precipitant to prepare cobalt oxide (Co3 O4 ) with precipitation method, then calcined at 300 and 500 °C, separately (named as C3 and C5). The Ni dopant (0.1 ~ 5 wt%) was added by deposited precipitation through Ni(NO3)2 ×6H2 O(aq) with drop wisely added NaOH(aq) into suspended Co3 O4 solution, then put the NaOCl for oxidation to obtain series 0.1%Ni-Co3 O4 , 0.2%Ni-Co3 O4 , 1%Ni-Co3 O4 and 5%Ni-Co3 O4 catalysts. All catalysts were characterized through BET, XRD, TEM/SEM, Raman, ICP and TPR instruments, and evaluated the catalytic performance of CO oxidation with a self-devised fluidized micro-reactor. It was observed that the calcination temperature and loading of dopant remarkably influenced the physicochemical characteristics and catalytic performance of the catalysts. Preferential catalyst was obtained for calcination at 300 °C and loading of Ni dopant below 1%. The doping of Ni on the surface of Co3 O4 enhanced the performance due to the inducing of synergistic effect between Co3 O4 and NiO, while the excessive NiO incorporated to the surface constrained the activity due to the abundant NiO on the surface, overlaying the active sites caused the decreasing of surface area and reducible capacity. Among these series Ni-Co3 O4 catalysts, the 0.2%Ni-Co3 O4 (C3) catalyst behaved an eminent activity with T50 of 98 °C and durability without apparent deactivation for 50 hr reaction at 125 °C. The excellent performance is primarily attributed to the synergistic effect and formation of NiCo2 O4 composite oxide.","PeriodicalId":20370,"journal":{"name":"Pollution Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70600061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Weed growth has greater space to grow during the initial slow vegetative phase of crop. Crop weed competition results in resource distribution, which significantly reduces crop yield. To understand the effect of different weed management practices on weed dynamics and productivity of chickpea, a field experiment was conducted at Forestry Research Farm, Department of Forestry, Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur (MP) during the Rabi season of 2020-21. The field experiment was laid out in randomized block design (RBD) with nine treatments and replicated thrice. Nine treatments were pendimethalin at 1000 g/ha, atrazine at 1000 g/ha, oxyflorfen at 100 g/ha, imazethapyr at 900 g/ha, pendimethalin at 500 g/ha + oxyflorfen at 50 g/ha, pendimethalin at 500 g/ha + imazethapyr at 450 g/ha, imazethapyr at 450 g/ha + atrazine at 500 g/ha, including hand weeding at 30 DAS and weedy check. The broad-leaf weeds, Medicago denticulate, Chenopodium album, Vicia sativa (L.) and Anagallis arvensis (L.) were dominant. In the case of grassy weeds, Cyperus rotundus (L.), Cynodon dactylon (Pers.) and Avena fatua (L.) are dominant weeds. Significant reduction in total weed density and dry weight was recorded under the application of pendimethalin at 500 g/ha + imazethapyr at 450 g/ha. In comparison, high values of growth parameters and seed yield were recorded with the application of pendimethalin at 1000 g/ha.","PeriodicalId":20370,"journal":{"name":"Pollution Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70600193","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
