Показано, что в случае повышения парциального давления паров воды при постоянном парциальном давлении кислорода (или водорода) в газовой фазе кажущийся уровень насыщения протонами увеличивается. Рост кажущегося уровня насыщения протонами происходит и при повышении парциального давления кислорода при постоянном парциальном давлении паров воды в газовой фазе. В работе обсуждались возможные причины наблюдаемых процессов. Методом изотопного обмена водорода с уравновешиванием изотопного состава газовой фазы проведены ис-следования процессов инкорпорирования водорода из атмосферы молекулярного водорода в структуру протон-проводящих оксидов на основе скандатов лантана. Определены концентрации протонов и дейтеронов в температурном интервале 300−800 °С и давлении водорода 0,2 кПа для оксида La0,91Sr0,09ScO3–α. В работе обсуждалась роль вакансий кислорода в процессе инкорпорирования протонов и дейтеронов из атмосферы молекулярного водорода в структуру протонпроводящих оксидов La1–xSrxScO3–α (x = 0; 0,04; 0,09). Методом протонного магнитного резонанса выполнены исследования локальной структуры в температур-ном диапазоне 23−110 °С при скорости вращения 10 кГц под магическим углом для оксида La0,96Sr0,04ScO3–α после термогравиметрических измерений в атмосфере, содержащей водяной пар, а также после выдержек в атмосфере молекулярного водорода. Однозначно показано существование протонных дефектов, инкорпорированных в объем исследуемого протонпроводящего оксида как из атмосферы, содержащей воду, так и из атомосферы, содержащей молекулярный водород. В работе рассмотрено влияние вкладов объема и поверхности оксида La0,96Sr0,04ScO3–α на форму спектров протонного магнитного резонанса</p></abstract><trans-abstract xml:lang="en"><p>The research uses the method of high-temperature thermogravimetric analysis to study the processes of interaction of the gas phase in the temperature range 300–950 °C in the partial pressure ranges of oxygen 8.1–50.7 kPa, water 6.1–24.3 kPa and hydrogen 4.1 kPa with La1–xSrxScO3–α oxides (x = 0; 0.04; 0.09). In the case of an increase in the partial pressure of water vapor at a constant partial pressure of oxygen (or hydrogen) in the gas phase, the apparent level of saturation of protons is shown to increase. An increase in the apparent level of saturation of protons of the sample also occurs with an increase in the partial pressure of oxygen at a constant partial pressure of water vapor in the gas phase. The paper discusses the causes of the observed processes. The research uses the hydrogen isotope exchange method with the equilibration of the isotope composition of the gas phase to study the incorporation of hydrogen into the structure of proton-conducting oxides based on strontium-doped lanthanum scandates. The concentrations of protons and deuterons were determined in the temperature range of 300–800 °C and a hydrogen pressure of 0.2 kPa for La0.91Sr0.09ScO3–α oxide. The paper discusses the role of oxygen vacancies in the process of incorporation of protons and deuterons from the atmosphere of molecular hydrogen into the structure of the proton conducting oxides La1–xSrxScO3–α (x = 0; 0.04; 0.09). The proton magnetic resonance method was used to study the local structure in the temperature range 23–110 °C at a rotation speed of 10 kHz (MAS) for La0.96Sr0.04ScO3–α oxide after thermogravimetric measurements in an atmosphere containing water vapor, and after exposures in molecular hydrogen atmosphere. The existence of proton defects incorporated into the volume of the investigated proton oxide from both the atmosphere containing water and the atmosphere containing molecular hydrogen is unambiguously shown. The paper considers the effect of the contributions of the volume and surface of La0.96Sr0.04ScO3–α oxide on the shape of the proton magnetic resonance spectra.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>термогравиметрия</kwd><kwd>ядерный магнитный резонанс</kwd><kwd>изотопный обмен водорода</kwd><kwd>скандат лантана-стронция</kwd><kwd>гидратация</kwd><kwd>окисление</kwd><kwd>гидрирование</kwd><kwd>протонпроводящие оксиды</kwd><kwd>водородная энергетика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>TGA</kwd><kwd>1Н NMR</kwd><kwd>hydrogen isotope exchange</kwd><kwd>lanthanum-strontium scandate</kwd><kwd>hydration</kwd><kwd>oxidation</kwd><kwd>hydrogenation</kwd><kwd>proton-conducting oxides</kwd><kwd>hydrogen power generation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной финансовой поддержке грантов Российского научного фонда (№ 16-13-00053-П) с использованием оборудования Центра коллективного пользования «Состав вещества» и УНУ «Изотопный обмен» ИВТЭ УрО РАН.
